Inbound Calling Issue

JZegers · March 2012

OK so working in my lab trying to get CUCM fully functional. Phones are registering in CUCM no problem, can call extensions, no problem, can make OUTBOUND calls, no problem. My issue is with inbound calls.

I make an inbound call from an external number, the phone registered through CUCM RINGS, but when i answer it, the inbound calling phone continues to ring, and i eventually get a busy signal.

I am using a 2801 with a SIP trunk to my provider, and using an H323 gateway to my call manager.

Heres what my config looks like:

2801CME#

The one and only route pattern i have in CUCM is 9.@, but i dont feel like that is the issue.

I feel the issue is somewhere with the H323 call setup but im stuck :S

ANY help at all? Can provide screens from call manager if needed.

You have a inbound and outbound dial-peers which is good. Are you sending the call to CUCM. Do a debug voice dial-peer to see what dial peer you are matching to send the call inbound to call manager. Then on that dial-peer check it out to make sure thats legit. You may also have to check your inbound gateway setting to make sure there is nothing funky in there. Debug voice ccapi is also a good command to find out if there are any type of rejections. You can run that one instead of the debug voice dialpeer

I am sending it to the CUCM server, i know the peer is working because the phone actually RINGS that is registered with CUCM, its just that when i pick up, the inbound phone continues to ring then i get a busy signal after a bit. Its like when i pickup the phone from CUCM it doesnt get the off hook signal.

hmmmm... Since you are using SIP it seems like your SIP messages aren't registering.

Do a

Debug ccsip messages
Debug ccsip calls

Sip between phones or sip between the CM and my Gateway? Does a h323 gateway actually use SIP for call signaling?

JZegers · March 2012

When i do a show h323 calls while the phone is ringing this is what i have, everything look normal? Again this is with the CUCM REGISTERED phone ringing with the inbound call from the outside:
