Zone A contains CCM 3.2 with IP phones. CCM is registered with GK-A.
Zone B contains GK-B with PSTN gateways.
When I call from an IP phone to the PSTN, I want to use the proxy functionality. I've got use-proxy commands set correctly for calls between the zones. The RTP flow should be as follows: Ip phone <-> GK A <-> GK B <-> PSTN GW
All gateways are registered correctly, I think the proxy is configured correctly. I think the problem is between CCM and GK-A. I've currently got a route pattern mapped to anonymous devices for the PSTN.
What happens is I place a call to the PSTN from an IP phone. The called party rings a couple of times before the call disconnects (before answer). If I pick up within 2 rings, the same happens- i.e. disconnect before any audio path is setup.
Is my scenerio possible? Any ideas? I have calls coming in from the PSTN to the IP phone through the proxy without any problems.
The symptoms are similiar when the codec negotiation fails. So check the codec negotiation of h323 signalling and see whether it is sucessfull. ( between the Proxy and the gateways - also check the CCM logs)
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
If you have 2 ISR routers, one acting as Failover, do we need to have both the same number of SRST licenses on the 2 routers?
No. You will only need the SRST licenses on the primary router. Because this feature...
