Patent ID: 7154999

Claim:
An apparatus, comprising: a first communication session control component that supports a first communication device on a communication session with a second communication device; and a second communication session control component that supports the second communication device on the communication session; wherein the first communication session control component stores a first call record that contains identification information of the first and second communication devices that are active on the communication session, and wherein the second communication session control component stores a second call record that contains the identification information of the first and second communication devices that are active on the communication session; wherein the first communication session control component sends the identification information of the first and second communication devices to a third communication session control component that supports a third communication device to invite the third communication device to join the communication session; and wherein if the third communication device joins the communication session, the first communication session control component adds identification information of the third communication device to the first call record and sends the identification information of the third communication device to the second communication session control component; and wherein upon receipt of the identification information of the third communication device from the first communication session control component, the second communication session control component adds the identification information of the third communication device to the second call record; and wherein if the identification information of the second communication device is unavailable to the first communication session control component, then the first communication session control component sets a telephone number for the second communication device to unknown to alert a user of the third communication device that the second communication device is active on the communications session.
