Solved: Gateway 2921 Incoming Calls CUCM

Claudio Quiroz Cabello · ‎10-19-2012

Hello Friends,

I´m working with CUCM. Last friday incoming calls don´t work in gateway 2921, however out calls and internal calls don´t have problem. Principal number is 756 2300. Exist translation rules into 2921 and CUCM, this is 6300.

Do you think pattern XX is the problem? Any idea?

Please, watch configuration...

Hi Claudio,

So to clarify when the VPN is connected you have incoming issues to DNs in Chile when the gateway is registered via MGCP with CallManger in Peru?

If I have understood the above correctly then is fallback SRST inbound is working fine, so the problem I suspect is the translation patterns in CUCM applied to the incoming gateway CSS. Have you confirmed these are in order?

I can see from your updated post that the output indicates that the gateway is unregistered with the CUCM mgcp call agent. I assume that the VPN is connected at this point? This would definitely be an issue if this was true, what is confusing is your statement that outbound calls work when the VPN is up? If the VPN is connected that I would expect ip phones to register to the CUCM in Peru and follow the CUCM route pattern and associated route-list. The route-list would contain a route-group consisting of the mgcp gateway. If you have a second mgcp gateway in this group then it is likely that this is the outgoing gateway,

If ip phones are able to register when the VPN. Is connected the I would look at any rules on the VPN gateway which is possibly restricting mgcp traffic.

Please rate helpful posts. Thank you.

Allan

Please post "debug isdn q931".

Not sure why you stated this is CME as this is a CUCM GW configuration, so also ensure the MGCP GW configuration in CUCM is accurate.

Hi Claudio,

Ideally you need to debug isdn q931 during the time that you are having problems with your incoming calls as Chris suggested. This will enable you to determine whether you are having problems with channel availability. The important aspect here is understanding whether the gateway was registered to CUCM or in H.323 fallback state when you had incoming problems? Can you post the show ccm-manager output this will indicate the last mgcp failover event.

I suspect that your gateway was possibly operating in fallback and either there was a channel issue on time-slot 1 which affected all incoming calls on this slot or either your actual translation rules failed to match the digits presented by your carrier. Are you aware of how many digits your carrier is presenting, the debug isdn q931 will indicate this during an incoming call.

Hi Allan,

2921 is in Chile and CUCM is in Peru. Exist VPN between them, Internal telephony is trought VPN connection. When VPN is out local incoming calls work perfectly and problem dissapear. SRST 2921 works perfectly. When VPN is in, the problem goes on.
