IP2IP Gateway one site calling issue

Hi Rajesh,

     We are getting a Cancel messgae from the remote voice gateway even before the call connects, i.e. before a 200 OK:

010891: Jul 24 15:27:43 UAE: //-1/xxxxxxxxxxxx/SIP/Msg/ccsipDisplayMsg:


CANCEL sip:7982@ SIP/2.0

Via: SIP/2.0/UDP;branch=z9hG4bK16DC70

From: "Henry, SOW" <1839>;tag=DA8F4EFC-1FE1

To: <7982>

Date: Wed, 24 Jul 2013 11:24:44 GMT

Call-ID: 79837B79-F38A11E2-8048A31C-80EE29B1@

CSeq: 101 CANCEL

Max-Forwards: 70

Timestamp: 1374665107

Reason: Q.850;cause=16

Content-Length: 0

Do we have the access to the remote gateway? If so, can we get the debugs from it too? Also does extension 1839 exist on the Gateway ( i.e. its a CME ) or does it exist on another CUCM cluster? If it is a CUCM cluster, what protocol is used between the gateway and the server?

Re: IP2IP Gateway one site calling issue

Extension is very much exists there, I am able to call and talk to them as we'll. but the issue is happening only when they calls us. I will try to get the logs from remote end

update : please find the latest logs from both the ends

Thanks / Rajesh
