I configured FXS port of VG310 in CUCM with MGCP. Want to know the call flow?
I configured a FXS a port with extension 1234 at port 0/0/1. In the VG310 end MGCP configuration is perfect. And configured a DP for the above port where it reflects mgcpapp .
Can you help me to understand the exact call flow here if someone calls 1234?
With MGCP all signalling and call routing is handled by CUCM and not the gateway, as is the case with SIP or H.323.
