SIP Virtual Mobile Extension
Description
Virtual Mobile Extension (VMEX) is a proprietary regional FMC (Fixed Mobile Convergence)
implementation, which combines mobile service with SIP Call services and the Summit system
functionality. Calls from the VMEX are directed from the Mobile Switching office to the carrier’s
SIP Call server and delivered to the Summit for routing. The Summit routes the call internally or
externally or activates a feature based on the digits received in the SIP “Invite” message.
When the Summit receives a call for the VMEX, the call is directed to the VMEX over a SIP trunk
to the carrier’s SIP Call server, which routes the call to the Mobile switching office to the VMEX.
Support for SIP Subscribe and Notify provide status updates to other devices within the Summit.
