ABSTRACT:
By modifying the communication endpoints to be presence aware and connecting them to a presence network, communication connections can be created wherein networks are added, or dropped, from the connection in order to keep the connection seamless from the perspective of the parties to the communication session. In one embodiment, an initiating user initiates a communication session on a first network (for example, a cellular network) to a target user served by a second network. During the communication session, the initiating user moves from his/her car to a landline and the communication session is transferred to a plain old telephone system (POTS) network. In one embodiment, on the target user's communication device an avatar representing the initiating user is updated to reflect that a landline network has been substituted for the cellular network.
