Call flow for VG310 configured in CUCM with MGCP

Hi Experts,

 

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.

This is a brief document that will help you better understand: Understanding MGCP Interactions with Cisco CallManager.

When 1234 is dialed, CUCM DA will return the MGCP end point which is the FXS port on the VG 310. CUCM will send a CRCX to initiate the call with the GW.
