Omotayo, When integrating CUCME and CUE it is best to use sip-notify vs. rtp-nte for dtmf configured on the dial-peer.
dial-peer voice 3160 voip > destination-pattern 3[16]00 > session protocol sipv2 > session target ipv4:10.10.202.2 > incoming called-number 399[89].... > dtmf-relay sip-notify > codec g711ulaw > no vad The dtmf-relay rtp-nte command sets the SIP DTMF relay mechanism to use the media path to relay incoming and outgoing DTMF signals to Cisco Unity Express. The dtmf-relay sip-notify command sets the SIP DTMF relay mechanism to use Unsolicited-Notify messages to relay incoming and outgoing DTMF signals.
