Abstract:
Devices, systems and methods are provided to support a party call with auto joining function in a communication system for a distributed transport system that employs VoIP technology. A VoIP unit or end point acts as a conference bridge between an operator extension and other end points. A first end point makes a SIP call to the operator and multicasts a mix of its send audio and the received operator audio. Other end points first check for multicast traffic being received before making a SIP call to the operator and, if so, play out the received audio over its speaker and multicast its send audio. The end point initiating the call mixes this subsequent stream into a stream to the operator, effectively acting as the conference bridge to the operator. The other end points are responsible for mixing received multicast streams for their local speaker.

Claim (Index 9):
A method of automatically joining party line communication among plural voice over internet protocol (VoIP) units operating as end points in an IP network comprising:\n registering plural VoIP units in an IP network with a Session Initiation Protocol (SIP) server to support point-to-point and multicast communications among them; a first VoIP unit initiating a call to a second VoIP unit selected from among the plural VoIP units, the first VoIP unit mixing two audio streams together comprising the first VoIP unit's send audio to the second VoIP unit and the second VoIP unit's send audio to the first VoIP unit, and retransmitting the two mixed audio streams as a multicast stream on a first multicast channel to the plurality of the VoIP units; a third VoIP unit from among the plurality of the VoIP units determining if a multicast stream associated with the second VoIP unit is present before initiating a call to the second VoIP unit; if the third VoIP unit determines that a multicast stream associated with the second VoIP unit is present, then the third VoIP unit uses the first multicast channel associated with the second VoIP unit as send audio from the second VoIP unit and transmits the third VoIP unit's send audio on a second multicast channel; the first VoIP unit mixing the third VoIP unit's send audio from the second multicast channel into the first VoIP unit's multicast stream that is broadcast to the other VoIP units
