Abstract
A system for switching from a first communication session between two endpoints to a secondary communication session when media degradation is detected is disclosed. A first endpoint is included within a first enterprise network and a second endpoint is included within a second enterprise network. The first enterprise network includes a call controller and a plurality of session border controllers (SBCs). The SBC in the first communication session detects media degradation and notifies the first endpoint of the media degradation. The first endpoint directs the call controller to establish a secondary communication session with the second endpoint when there is sufficient media degradation. The call controller directs a second SBC to establish the secondary communication session with the second endpoint. When the secondary communication session is established, the call controller directs the first endpoint to send media data using the second SBC.
