DTMF issue

[Suchi]

Hello,

I  have below setup, but DTMF doesn't work. What is the recommended DTMF config?

CUCM----H323----CUBE---SIP TRUNK ---ITSP

Dial Peer config :

dial-peer voice 333 voip
 description Incoming VoIP Dial-Peer from CUCM
 incoming called-number .
 voice-class codec 1  
 voice-class h323 1
 dtmf-relay h245-alphanumeric rtp-nte
 no vad

dial-peer voice 100 voip
 description Local Calls
 translation-profile outgoing 3
 preference 1
 destination-pattern 0[2-9].......
 session protocol sipv2
 session target ipv4:172.33.40.6
 voice-class codec 1  
 dtmf-relay h245-alphanumeric rtp-nte
 no vad

Dial-peer 100 is SIP dial-peer yet you configured H323 DTMF method as the primary. Change it to "dtmf-relay rtp-nte sip-kpml". I would also recommend that you re-configure the integration between CUCM and CUBE to SIP trunk instead of H.323 GW, this way you will have end to end SIP and same DTMF method. Another issue is that your Dial-peer 333 is H323 DP and matches on all incoming numbers, hence it would be the default inbound dial-peer for calls arriving from PSTN, and unless you have other dial-peer with other inbound matching this will also be a problem.
