Disclosed are techniques for hosting a communication session in a call server between communication devices. The call server functions as a bridge service between the communication devices joining an original communication link between the first communication device and the call server with a second communication link between the second communication device and the call server. The first communication device includes at least two RF transceivers each capable of communicating with the call server over a separate network. The call server receives a signal from the first communication device indicative of the need to handoff the original communication link to an alternate communication link on an alternate network. The call server establishes the alternate communication link with the first communication device on the alternate network and joins it with the second communication link to maintain the communication session between the communication devices. |
