         [0079]      FIG. 1  illustrates an exemplary audio caller communication system  1 S comprising an audio unit  8  configured to sound a voice sound  10 X from an audio callee communication system  1 R to a user  2  using the system in an intended way The audio unit  8  may comprise a microphone  11  to receive a voice sound  10  from the user  2 . Additionally, the audio caller communication system  1 S may comprise a position unit  19  configured to estimate a caller position  26 S. Additionally, the audio caller communication system  1 S may comprise an orientation unit  18  configured for estimating a current caller orientation  13 S of the audio caller communication system  1 S. Furthermore, the orientation unit  18  may be configured for estimating a caller field of view  12 S in the caller orientation  13 S of the audio caller communication system  1 S. 
         [0080]    The audio caller communication system  1 S may be configured with a caller ID IDA, which ID is a public network ID like a telephone number, an Internet ID or any other communications network ID in a public communication network  17 . 
         [0081]    The audio callee communication system  1 R will be described in  FIG. 2  to which a reference is hereby made. Likewise, specifics of a shared connection server  30  are described in  FIGS. 2 and 3 . 
         [0082]    The audio caller communication system  1 S and the audio callee communication system  1 R are configured to be able connect so that a user  2  being a caller can call, connect, and communicate with a user  2 X of an audio callee communications system  1 R through a public communications network  17 . 
         [0083]    The audio caller communications system  1 S may be configured to make a caller position  26 S available to a shared connection server  30 . This may be in such a way that the caller ID IDA of the caller  1 S is linked to the caller position  26 S. The audio caller communications system  1 S may be configured to make a caller orientation  13 S available to a shared connection server  30 . This may be in such a way that the IDA of the caller  1 S is linked to the caller orientation  13 S. 
         [0084]    The availability of a caller ID say IDA may be present without disclosing the call ID (IDA) to a callee  18 . As such the call is an anonymous call. 
         [0085]    In this case, the audio caller communication system  1 S is enabled via a shared connection server  30  for a call signal  4 X to at least an audio callee communication system  1 R. 
         [0086]    In this particular example, the audio callee communication system  1 R is configured for communicating  4  with the audio caller communication system  1 S via the public communication network  17  and/or the shared connection server  30 . 
         [0087]    The audio caller communication system  1 S may be configured so that the caller ID IDA is made available as the call signal  4 X to an audio callee communication system  1 R as a function  34  of the current caller position  26 S and/or the at least one caller orientation  13 S estimated by the audio caller communication system  1 S. When a call is accepted, an open communication channel ( 5 ,  6 ) is made between the caller  1 S with a caller ID IDA or IDS and a callee  1 R with a callee ID. In a particular example, the caller ID IDA or IDS may not be made available to the audio callee communication system  1 R. 
         [0088]    Furthermore, the communication channel  5  between the audio caller communication system  1 S and another callee communication system  1 RX may be closed  7 . However, the caller communication system  1 S may still be available for a connection as a function  34  of the current caller position  26 S and/or the at least one caller orientation  13 S. 
         [0089]    Additionally, the shared connection server  30  may be configured to handle connections between more than one other audio caller communication system  1 SX and more than one other audio callee communication system  1 RX. Likewise, the audio caller communication system  1 S may be configured to handle more connections to audio callee communication systems  1 R. 
         [0090]    Alternatively, the current caller position  26 S and/or the current caller orientation  13 S linked to the caller ID (IDA) of the audio caller communication system  1 S are made publically available via the shared connection server  30  for a call signal  4 X to the at least one audio callee communication system  1 R. 
         [0091]    Alternatively, the audio caller communications system  1 S may be configured for transferring data  31  via data communication channel  5 X when a connection is made available via an available caller ID IDA. 
         [0092]      FIG. 2  illustrates, in continuation of  FIG. 1 , an exemplary audio callee communication system  1 R comprising an audio unit  8  configured to sound a voice sound  10 X from an audio caller communication system  1 S to a user  2  using the audio callee communication system  1 R in an intended way. The audio unit  8  may comprise a microphone  11  receiving a voice sound  10  from the user  2 . Additionally, the audio callee communication system  1 R may comprise a position unit  19  rendering a callee position  26 R. 
         [0093]    The audio callee communication system  1 R may be configured with at least one call identification (ID), which identification ID is a public network ID like a telephone number, an Internet ID or any other communications network ID in a public communication network  17 . 
         [0094]    The audio callee communication system  1 R may be configured to communicate  4  with a shared connection server  30  about the current position  26 R and the callee ID ID 0  of the audio callee communication system  1 R. 
         [0095]    The audio callee communication system  1 R may be configured so that the callee ID ID 0  is made available via a shared connection server  30  for a call signal  4 X from the at least one audio caller communication system  1 S for a connection through the communications channel  5  as a function  34  of at least the current callee position  26 R. 
         [0096]    In this particular example, the audio caller communication system  1 S communicates with the audio callee communication system  1 R via the public communication network  17  and/or the shared connection server  30  and the audio callee communication system  1 R accepts a call signal  4 X from the audio caller communication system  1 S via the shared connection server  30 . When the call signal  4 X is accepted, an open communication channel ( 5 ,  6 ) is made between the caller  1 S with a caller ID IDA or IDS and a callee  1 R with a callee ID ID 0 . In a particular example, the caller ID IDA or IDS may not be made available to the audio callee communication system  1 R. 
         [0097]    Furthermore, the communication channel  5  between the audio caller communication system  1 S and another callee communication system  1 RX may be closed  7 . However, the callee communication system  1 S may still be available for a connection as a function  34  of the current callee position  26 R. 
         [0098]    Additionally, the shared connection server  30  may be configured to handle connections between more than one other audio caller communication system  1 SX and more than one other audio callee communication system  1 RX. Likewise, the audio callee communication system  1 R may be configured to handle more connections to audio caller communication systems  1 S. 
         [0099]    Alternatively, the current callee position  26 R linked to the call ID (IDR) of the audio callee communication system  1 R may be made publically available via the shared connection server  30  for the call signal  4 X by at least one audio caller communication system  1 S. 
         [0100]    Additionally, the audio callee communication system  1 R may be configured as an audio caller communication system ( 1 S) and vice versa. 
         [0101]      FIG. 3  illustrates an exemplary shared connection server  30  configured to communicate and interact with at least the audio caller communication system  1 S, see  FIG. 1 , and at least the audio callee communication system  1 R, see  FIG. 2 . 
         [0102]    The shared connection server  30  may be configured to connect to at least the audio caller communication system  1 S with at least the audio callee communication system  1 R through a communication channel  5 . The connection or the establishment of a open communication channel  5  may be as a function  34  of at least one callee position  26 R and at least one caller position  26 S and/or at least one caller orientation  13 S. 
         [0103]    In this particular example, the audio caller communication system  1 S is configured to connect to the audio callee communication system  1 R by communicating  4  via public network  17  through a communication channel  5  established by the shared connection server  30 . The audio caller communication system  1 S has made a caller ID IDA available via the shared connection server  30  for a call signal  4 X to the at least one callee ID ID 0  configured to the audio callee communication system  1 R. 
         [0104]    The connection between the at least audio caller communication system  1 S and the at least audio callee communication system  1 R is established through the communication channel  5  as a function of at least one callee position  26 R and/or at least one caller position  26 S and at least one caller orientation  13 S. 
         [0105]    The connection may be made in such a way that the call ID (ID 0 ) of the callee is not disclosed to the audio caller communication system  1 S. The connection may be made in such a way that the call ID (IDA) of the caller is not disclosed to the audio callee communication system  1 R. As such, the connection is made anonymously. Thus, the connection merely discloses the position of the callee and/or the caller to the respective counterpart. 
         [0106]    Alternatively, the function  34  may estimate a current caller position based on the caller position  26 S and the caller orientation  13 S. Additionally, the function  34  compares the estimated caller position and the callee position  26 R. If the estimated caller position is the same as the callee position  26 R an open communication channel ( 5 , 6 ) is established, or if the estimated caller position is the within a range of the callee position  26 R an open communication channel ( 5 , 6 ) is established. 
         [0107]    Alternatively, the public communication network  17  and the shared connection server  30  may be separated or combined. In an embodiment, the shared connection server  30  is established or configured in a public communication network  17 . In an alternative embodiment, the shared connection server  30  stands alone in the communication network. 
         [0108]      FIGS. 4A-D  illustrate an exemplary of an audio unit  8  comprising a portable network device  35  and/or a wearable hearing device  32 . 
         [0109]      FIG. 4A  illustrates an audio unit  8  comprising a portable network device  35  connected to a wearable headband hearing device  32 . In this particular example, the portable network device comprises a microphone, a position unit  19  and an orientation unit  18 .

         [0115]      FIGS. 5A-C  illustrate an exemplary audio caller communication system  1 S activating a call signal  4 X and when the call signal  4 X is accepted by the audio callee communication system  1 R an open communication channel ( 5 , 6 ) is established between the caller  1 S and the callee  1 R via a shared connection server  30 . 
         [0116]      FIG. 5A  illustrates an audio caller communication system  1 S configured with at least one caller ID IDA activating the call signal  4 X when the current callee position  26 R of the at least one audio callee communication system  1 R is a first encounter along a line of sight  14  in the direction of the caller orientation  13 S. 
         [0117]    In this particular example, the line of sight  14  of the audio caller communication system  1 S encounters firstly the current callee position  26 R of the audio callee communication system  1 R and activating the call signal  4 X. The call signal  4 X is accepted by the callee  1 R and an open communication channel ( 5 ,  6 ) is established between the caller  1 S and the callee  1 R via a shared connection server  30 . 
         [0118]    Alternatively, the communication channel  5  may be open  6  or closed  7  when a call signal  4 X is activated or deactivated, respectively. 
         [0119]    Alternatively, the caller ID (IDA) may be made publically available via the shared connection server  30  for the call signal  4 X to the at least one audio callee communication system  1 R without disclosing the caller ID (IDA) of the audio caller communication system  1 S to the at least one audio callee communication system  1 R. 
         [0120]    Alternatively, the callee ID (ID 0 ) may be made publically available via the shared connection server  30  for the call signal  4 X by at least one audio caller communication system  1 S without disclosing the callee ID (ID 0 ) of the audio callee communication system ( 1 R) to the at least one audio caller communication system  1 S. 
         [0121]    Alternatively, when a communication channel is established via the shared connection server  30  the audio caller communications system  1 S may be configured for transferring data  31  via data communication channel  5 X when a connection is made available via an anonymously available caller ID IDA. The data communication channel  5 X may be combined with the communication channel  5 . 
         [0122]    In another embodiment, the communication channel  5  may be closed  7  when an audio caller communication system  1 S or an audio callee communication system  1 R deactivates or declines the call signal  4 X. 
         [0123]      FIG. 5B  illustrates at least two audio caller communication systems ( 1 S,  1 SX), each activating a call signal  4 X via the shared connection server  30  to at least one audio callee communication system  1 R through the communication channel  5  which is open  6  when the callee accepts the call  4 X. 
         [0124]    Alternatively, the at least two audio caller communication systems ( 1 S,  1 SX) establish a communication group  33  with at least one audio callee communication system  1 R. 
         [0125]    The audio caller communication system  1 S is configured with at least one caller ID IDA and another audio caller communication system  1 SX is configured with at least one another caller ID IDZ. The at least one audio callee communication system  1 R is configured with at least one first anonymous callee ID ID 1 . The at least one audio callee communication system  1 R may receive a plurality of call signals  4 X from a plurality of audio caller communication systems ( 1 S,  1 SX). The at least one audio callee communication system  1 R may accept a plurality of calls  4 X establishing an open communication channel ( 5 , 6 ) between a plurality of audio caller communication systems ( 1 S,  1 SX) and the audio callee communication system  1 R via the shared connection server  30 . 
         [0126]    In this particular example, the call signals  4 X from the two callers ( 1 S,  1 SX) are activated when the two lines of sight  14  of the two audio caller communication systems ( 1 S, 1 SX) encounter first the current callee position  26 R of the audio callee communication system  1 R. The audio callee communication system  1 R accepts the call signals  4 X from both callers ( 1 S,  1 SX) establishing an open communication channel ( 5 , 6 ) between the plurality of audio caller communication systems ( 1 S,  1 SX) and the audio callee communication system  1 R via the shared connection server  30 . 
         [0127]      FIG. 5C  illustrates at least one audio caller communication system  1 S configured to activate a plurality of call signals  4 X to a plurality of audio callee communication systems ( 1 R,  1 RX) via the shared connection server  30 . 
         [0128]    The at least one audio caller communication system  1 S may be configured to communicate with more than one audio callee communication systems ( 1 R) via the shared connection server  30 . 
         [0129]    In this particular example, the line of sight  14  of the audio caller communication system  1 S is oriented towards the audio callee communication system which then encounters first the current callee position  26 R of the audio callee communication system  1 R. A call signal  4 X is activated via the shared connection server  30 . The callee  1 R accepts the call signal  4 X and an open communication channel ( 5 , 6 ) is established between the caller  1 S and the callee  1 R. 
         [0130]    Furthermore, the audio caller communication system  1 S changes the orientation of the line of sight  14  to another audio callee communication system  1 RX so that the line of sight  14  encounters first the current callee position  26 R of another audio callee communication system  1 RX. Another call signal  4 Z is activated via the shared connection server  30 . Another callee  1 RX accepts another call signal  4 Z and an open communication channel ( 5 , 6 ) is established between the caller  1 S and another callee  1 R. 
         [0131]    Thereby, the audio caller communication system  1 S has established a communication group  33  comprising at least two audio callee communication systems ( 1 R,  1 RX) and the audio caller communication system  1 S. 
         [0132]    Alternatively, caller ID IDA and/or callee ID IDO may be anonymous. 
         [0133]    Alternatively, the call signal  4 X may be deactivated or closed when the caller  1 S activates another call signal  4 Z. The call signal  4 X may be deactivated or closed when the caller  1 S activates another call signal  4 Z and another callee  1 RX accepts another call signal  4 Z. 
         [0134]      FIGS. 6A-C  illustrate an exemplary audio caller communication system  1 S activating a call signal  4 X and when the call signal  4 X is accepted by the audio callee communication system  1 R an open communication channel ( 5 , 6 ) is established between the caller  1 S and the callee  1 R via a shared connection server  30 . 
         [0135]      FIG. 6A  illustrates an audio caller communication system  1 S configured with at least one caller ID IDA. At least a first, a second and a third audio callee communication system ( 1 RA,  1 RB,  1 RC) are configured to at least a first, a second and a third callee ID (ID 1 , ID 2 , ID 3 ), respectively. 
         [0136]    The audio caller communication system  1 S may activate a call signal  4 X via the shared connection server  30  to the at least one first audio callee communication system  1 RA when a current callee position  26 R of the at least first audio callee communication system  1 RA is crossed by a sweep  20  of a line of sight  14  in the direction of the caller orientation  13 S. 
         [0137]    In this particular example, the audio caller communication system  1 S sweeps  20  the line of sight  14  crossing the current callee position  26 R of the at least first and second audio callee communication system ( 1 RA,  1 RB) activating a call signal  4 X to the first and second audio callee communication system ( 1 RA,  1 RB). The two callees ( 1 RA,  1 RB) accept the call signal  4 X from the caller  1 S, and between each of the callees ( 1 RA,  1 RB) and the caller  1 S an open communication channel ( 5 ,  6 ) is established via the shared connection server  30 . 
         [0138]    Alternatively, if the two callees ( 1 RA,  1 RB) accept the call signal  4 X from the caller  1 S, and between the callees ( 1 RA,  1 RB) and the caller  1 S a common open communication channel ( 5 ,  6 ) is established via the shared connection server  30 . 
         [0139]    Alternatively, the audio caller communication system  1 S and the audio callee communication system  1 R may be configured with a profile. The profile may be administrated by the user  2  of the caller  1 S or the callee  1 R. 
         [0140]    Alternatively, the speed of a sweep  20  may control a mode of an audio caller communication system  1 S. A fast sweep may change the status of the caller  1 S into an emergency mode, wherein the emergency mode may activate a plurality of call signals  4 X from the caller  1 S to a plurality of callees  1 R having a profile of a doctor. Furthermore, a normal sweep may change the status of the caller  1 S into a custom mode, wherein the custom mode may activate a call signal  4 X from the caller  1 S to at least one callee  1 R. 
         [0141]      FIG. 6B  illustrates that the audio caller communication system  1 S has increased the range of the sweep  20  of the line of sight  14 , compared to  FIG. 5 . The sweep crosses the current callee position  26 R of at least the three audio callee communication systems ( 1 EA,  1 RB,  1 RC) activating at least three call signals. All three callees ( 1 EA,  1 RB,  1 RC) accept the call signals  4 X and at least three communication channels are established between the caller  1 S and the three callees ( 1 EA,  1 RB,  1 RC) via the shared connection server  30 . 
         [0142]      FIG. 6C  illustrates an audio caller communication system activating a call signal to a plurality of callees ( 1 RB,  1 RC) by sweeping  20  the line of sight  14  crossing the callee position of each callees ( 1 RB,  1 RC). 
         [0143]    Another audio caller communication system activates a call signal to the same plurality of callees ( 1 RB,  1 RC) by sweeping  20  the line of sight  14  crossing the callee position of each of the callees ( 1 RB,  1 RC). 
         [0144]    Alternatively, each callees ( 1 RB,  1 RC) accepts the call signals  4 X from each callers ( 1 S,  1 SX) and a communication channel ( 5 , 6 ) is established between each of the callees ( 1 RB,  1 RC) and each callers ( 1 S,  1 SX). 
         [0145]    Alternatively, each of the callees ( 1 RB,  1 RC) accepts the call signals  4 X from each callers ( 1 S,  1 SX) and a common communication channel ( 5 , 6 ) is established between the callees ( 1 RB,  1 RC) and the callers ( 1 S,  1 SX). 
         [0146]    Alternatively, each of the callees ( 1 RB,  1 RC) accepts the call signals  4 X from each callers ( 1 S,  1 SX) and a communication channel ( 5 , 6 ) is established between the callees ( 1 RB,  1 RC) and each of the callers ( 1 S,  1 SX). 
         [0147]      FIGS. 6A-C  illustrate an exemplary audio caller communication system  1 S activating a call signal  4 X and when the call signal  4 X is accepted by the audio callee communication system  1 R an open communication channel ( 5 , 6 ) is established between the caller  1 S and the callee  1 R via a shared connection server  30 . 
         [0148]      FIGS. 7A-B  illustrate an exemplary audio caller communication system  1 S activating a call signal  4 X and when the call signal  4 X is accepted by the callee  1 R an open communication channel ( 5 , 6 ) is established between the caller  1 S and the callee  1 R via a shared connection server  30 . 
         [0149]      FIG. 7A  illustrates the audio caller communication system  1 S configured with at least one caller ID IDA. At least a first, a second, a third and a fourth audio callee communication system ( 1 RA,  1 RB,  1 RC,  1 RD) are configured with at least a first, a second, a third and a fourth callee ID (ID 1 , ID 2 , ID 3 , ID 4 ), respectively. The audio caller communication system  1 S may activate the call signal  4 X via the shared connection server  30  to the at least audio callee communication system  1 R when the current callee position  26 R of the at least one audio callee communication system  1 R is within an area of view  9  at a certain distance in the direction of the caller orientation ( 13 S). 
         [0150]    In this particular example, the area of view  9  of the audio caller communication system  1 S encloses the current callee position  26 R of the at least one, first and second audio callee communication system ( 1 RA,  1 RB). Thereby, the audio caller communication system  1 S activates a call signal  4 X to the first and the second audio callee communication systems ( 1 RA,  1 RB) via the shared connection server  30 . The callees ( 1 RA,  1 RB) accept the call signal  4 X and the open communication channel ( 5 , 6 ) is established. 
         [0151]      FIG. 7B  illustrates the audio caller communication system  1 S activating the call signal  4 X via the shared connection server  30  to the at least audio callee communication system  1 R when a current callee position  26 R of the at least one audio callee communication system  1 R is tracking  15  for a period of time by the audio caller communications system  1 S configured to a current caller position  26 S. 
         [0152]    In this particular example, the audio caller communication system  1 S is moving among a plurality of callees ( 1 RA- 1 RC). The caller  1 S is tracking  15  behind a first callee  1 RA for a period of time wanting to establish a communication to the first callee  1 RA. After the period of time the call signal  4 X is activated and an open communication channel ( 5 ,  6 ) is established between the caller  1 S and the first callee  1 RA. 
         [0153]      FIGS. 8A-B  illustrate an exemplary audio caller communication system  1 S activating a call signal  4 X via a shared connection server  30  to at least one audio callee communication system  1 R through a communication channel  5  which is open  6 . The audio caller communication system  1 S is configured to at least one caller ID IDA and the at least one audio callee communication system  1 R is configured to at least one callee ID ID 0 . 
         [0154]    The audio caller communication system  1 S is configured to a caller opening distance D S  and the audio callee communication system  1 R is configured to a callee opening distance D R . 
         [0155]      FIG. 8A  illustrates that the caller and the callee opening distance (D R , D S ) are not overlapping, and thereby, no call signal  4 X is activated. The audio callee communication system  1 R has activated the callee ID ID 0  via the shared connection server  30 . 
         [0156]      FIG. 8B  illustrates the caller and the callee opening distance (D R , D S ) overlapping, and thereby, a call signal  4 X is activated via the shared connection server  30  from the audio caller communication system  1 S to the audio callee communication system  1 R. 
         [0157]      FIGS. 9A-B  illustrate an exemplary audio caller communication system  1 S activating a call signal  4 X via a shared connection server  30  to at least one audio callee communication system  1 R through a communication channel  5  which is open  6 . The audio caller communication system  1 S is configured to at least one anonymous caller ID IDA and the at least one audio callee communication system  1 R is configured to at least one anonymous callee ID ID 0 . 
         [0158]    The audio caller communication system  1 S is configured to a caller field of view  12 S in the caller orientation  13 S. 
         [0159]      FIG. 9A  illustrates that the audio caller communication system  1 S has oriented  13 S the field of view  12 S away from the audio callee communication system  1 R, and thereby, no call signal  4 X is activated. The audio callee communication system  1 R has activated the callee ID ID 0  via the shared connection server  30 . 
         [0160]      FIG. 9B  illustrates the audio caller communication system  1 S activating the call signal ( 4 X) via the shared connection server  30  to the at least audio callee communication system  1 R when the current callee position  26 R of the audio callee communication system  1 R is within the caller field of view  12 S of the audio caller communication system  1 S. 
         [0161]      FIG. 10  illustrates a situation where an audio caller communication system  1 S is walking around on a square with a plurality of audio callee communication systems ( 1 RA- 1 RE). Each audio callee communication system is configured to a callee profile CP. 
         [0162]    A first, a third and a fifth audio callee communication system ( 1 RA,  1 RC,  1 RE) has not defined a callee profile CP. A second and a fourth callee communication system ( 1 RB,  1 RD) has defined same callee profile CP, which in this particular example is disclosing a profile of a doctor. A sixth audio callee communication system  1 RF has defined a callee profile CP, which in this particular example is disclosing a profile of a policeman. 
         [0163]    Furthermore, the audio caller communication system  1 S is configured to activate the call signal  4 X via the shared connection server  30  when the current callee position  26 R of the at least one audio callee communication system  1 R has the preferred callee profile CP within an area of view  9  at a certain distance in the direction of the caller orientation  13 S. 
         [0164]    In this particular example, the user  2  configured to the audio caller communication system  1 S suddenly sees a person in need of medical attention  36 . The user  2  immediately initializes the audio caller communication system  1 S activating a call signal  4 X to at least one audio callee communication system ( 1 RB,  1 RD) having a callee profile CP disclosing a profile of a doctor or a nurse. 
         [0165]    The area of view  9  configured to the audio caller communication system  1 S is oriented  13 S towards a crowd, and immediately a plurality of call signals  4 X is activated via the shared connection server  30  to the second and the fourth audio callee communication system ( 1 RB,  1 RD). Both callees ( 1 RB,  1 RD) have a callee profile of a doctor. A communication group  33  is formed comprising the audio caller communication system  1 S and the first and the second audio callee communication system ( 1 RB,  1 RD). The user  2  configured to the audio caller communication system  1 S communicates with the first and the second audio callee communication system ( 1 RB,  1 RD) through the established communication channel ( 5 ,  6 ). The caller  1 S guides the two callees ( 1 RB,  1 RD) to the person in need of medical attention  36 .
