Hi Thiago,
For such issues, it's always best to provide details like versions and the call flow. From what I see from the trace file, the call flow looks like this (correct me if I'm wrong):
PSTN -- H323 Gateway -- CUCM -- IP Phone 1 (SCCP)
|
IP Phone 2 (SIP)
I see the following in the SDI file:
09:41:57.136 |MediaManager(111412)::wait_AuConnectRequest, CI(28219037,28219042), capCount(1,0), mcNodeId(0,0), xferMode(7,16), reConnectType(0), mrid (0, 0) IFCreated(1 1) proIns(52795 25483), AC(1,0) party1DTMF(1 1 0 1 0) party2DTMF(1 2 101 0 0),reConnFlag=0, connType(3,3), IFHand(0,0),MTP(0,0),MRGL(af3fcea5-f224-2e5a-6ab5-1c9901bc5d41,af3fcea5-f224-2e5a-6ab5-1c9901bc5d41) videoCap(0 0), mmCallType(0),FS(0,0) IpAddrMode(0 0) aPid(1, 177, 73627), bPid(1, 68, 31606) EOType(0 0)|1,100,220,1.5231046^172.23.0.130^*
The 2 Call Identifiers are the final legs which need to be joined i.e. the original H323 leg and the SIP leg. However, you can see that there is a DTMF mismatch. H323 leg can do OOB while SIP leg can do RFC2833. Hence MTP is required. UCM tries to invoke MTP:
09:41:57.136 |MediaManager(111412)::isMTPNeededForDTMF, isMTPNeeded(1)|1,100,220,1.5231046^172.23.0.130^*
09:41:57.137 |MediaResourceManager::waiting_MrmAllocateMtpResourceReq CI=28219045, Count=2|1,100,220,1.5231046^172.23.0.130^*
09:41:57.140 |MediaResourceCdpc(28863)::createLookupTbl Name=MTP_2 Cepn=8744afa4-c5d9-4531-a071-a01fd086f49a Weight=0 Group=0 Counter=0|1,100,220,1.5231046^172.23.0.130^*
09:41:57.140 |MediaResourceCdpc(28863)::createLookupTbl Name=XCODER Cepn=37196750-73be-d7dc-ab80-34afddf5a41e Weight=0 Group=2 Counter=4|1,100,220,1.5231046^172.23.0.130^*
However, both of them fail to get allocated due to device cap mismatch.
MTP_2 error:
09:41:57.140 |MediaTerminationPointControl(1)::getResourcesAllocated -- No matching caps for either side A or side B, MTP not allocated|1,100,220,1.5231046^172.23.0.130^*
XCODER error:
09:41:57.141 |MediaTerminationPointControl(12)::waiting_AllocateMtpResourceReq - ERROR out of resource|1,100,220,1.5231046^172.23.0.130^*
I would suggest checking and making sure that the region setting between the H323 gateway and MTP_2 as well as SIP Phone and MTP_2 is set to the same codec. In this case, it seems to be negotiating G729 codec which is possibly why the software MTP is not getting allocated. It tries XCODER but also fails. I would also doublecheck your xcode / hardware MTP to make sure it is configured properly, is registered and has enough sessions to support this call.
HTH.
