[cisco-voip] DTMF Issue with SIP TRUNK (CUCM -- SIP Trunk---- CUCME<---CUE)

[Brian Meade (brmeade)]

Viki,

What do you see getting negotiated for DTMF on the CUCM side?  You might want to try forcing out-of-band on the CUCM side.  Try changing the DTMF Signaling Method to "OOB and RFC 2833".

Hello All,
I am facing an issue with dtmf-relay. PhoneA registered to CUCM (SiteA) calls PhoneD registered to CUCME (Site C). Between Regions G729 codec is negotiated. PhoneD call-forward no answer to Voicemail. CUE integrated with CME. After leaving the Voicemail from PhoneA to PhoneD, when I press # key to send the Voicemail, it is not recognized.
Here is my scenario and the configuration.
(PhoneA) -- CUCM ----SIP TRUNK ----CUCME (PhoneD) ---> CUE.

On the CUCM, I did the following,

Media Termination Point Required (Checked)
MTP Preferred Originating CodecRequired Field: g711ulaw
DTMF Signaling MethodRequired Field: No preference
Non Secure SIP Trunk Profile: I am using TCP+UDP for INCOMING + Accept Unsolicited Notification (Checked).
Please let me know what I am missing.
Thanks,
Viki
