I want to integrate FXO port with CCM4.1. For this, I installed VIC2-2FXO on 2811 router with 12.3(8r)T7 IOS. I configured the following to turn ON MGCP on this gateway.
mgcp call-agent 10.3.1.196 service-type mgcp version 0.1
mgcp dtmf-relay voip codec all mode cisco
mgcp validate domain-name
Than I added this gateway on the CCM. CCM correctly detected the installed FXO ports on router. I configured the port in Loop start mode and forwarded the incoming call on FXO to one of my extension. When call is received on router, I had to give the PLAR and voip dial peer to forward the call to CCM.
connection plar 4584
dial-peer voice 100 voip
session target ipv4:10.3.1.196
Incoming call is fine but I cant see the caller ID. It says Unknown Number !!! Any help??
For making outgoing calls, I added a calling search space, a route list with the MGCP gateway and assigned the calling search space to a DN where incoming calls are forwarded. I also configured a pots dial peer that matches the fxo port. Configuration is:
dial-peer voice 1000 pots
6.T is because I have cofigured the route pattern to drop the pre dot digits and append 6 to the destination pattern. This destination pattern matches the pots dial peer and should make a call. But call is not going through. After I dial the digits, I hear the fast busy tone. Please any help?
