Abstract

See full text

A method includes receiving, at a first communication service provider, a request (by a first device and including identification information associated with a particular user of a second device) to initiate a session between the first device and the second device for a multimedia service provided by a second communication service provider. The method includes determining access information associated with the second device based on the identification information and sending a call invitation to the second device to initiate the session. Accepting the call invitation causes the second device to receive the particular application (which is executable to facilitate initiation of the session) from the second communication service provider via a connection between the second device and the second communication service provider.
