Raaj,

I looked at these traces and see the MTP is being pulled in due to the
early offer configuration but would also be needed for the DTMF mismatch:
20:20:05.285 |MediaManager(710186)::wait_AuConnectRequest,
CI(48708178,48708179), capCount(11,1), mcNodeId(0,0), xferMode(12,16),
reConnectType(0), mrid (0, 0) IFCreated(0 0) proIns(0 0), AC(0,0)
party1DTMF(1 1 0 1 0) party2DTMF(3 2 101 1 0),reConnFlag=0, connType(3,3),
IFHand(0,0),MTP(0,0),MRGL(aaf6462d-d96d-8d78-e98b-f96a899cd470,aaf6462d-d96d-8d78-e98b-f96a899cd470)
videoCap(0 0), mmCallType(0),FS(0,0) IpAddrMode(0 0) aPid(2, 135, 1366),
bPid(2, 68, 209650) EOType(0 2)|2,100,57,1.1030654^10.14.0.46^*

20:20:05.285 |MediaManager(710186)::isMTPNeededForDTMF,
isMTPNeeded(1)|2,100,57,1.1030654^10.14.0.46^*

party1 only supports out of band and party 2 only supports in-band.  It
looks like the SIP Trunk has a DTMF Preference hard set as well.

As far as only getting 1 digit, I only see one digit actually being sent by
the MGCP gateway:
20:20:11.021 |MGCPHandler received msg from: 10.128.0.2
NTFY 200530244 S0/SU0/DS1-0/11 at 10.128.0.2 MGCP 0.1
N: ca at 10.128.4.10:2427
X: b
O: D/1
|2,100,152,1.5777096^10.128.0.2^*


CUCM sends a request notification to continue receiving any future digits:
20:20:11.022 |MGCPHandler send msg SUCCESSFULLY to: 10.128.0.2
RQNT 1863107 S0/SU0/DS1-0/11 at 10.128.0.2 MGCP 0.1
X: b
R: D/[0-9ABCD*#]
Q: process,loop

But the gateway never seems to send any further digits.
