I believe it will not work since the conversion of dtmf digits from h245-a to
rtp-nte is not supported on Cisco SIP trunk side.

Hi, I'm trying to make DTMF digits be recognize by Unity from CME calls through
a IPIPGW. This is the topology:
CME Phone ---h323---> IPIPGW----SIP---->Unity
Please, May someone give me a suggestion? Thank You!
This is the config at CME:
dial-peer voice 21 voip
preference 1
destination-pattern [12]...
voice-class codec 1
voice-class h323 1
session target ipv4:10.2.200.21
dtmf-relay h245-alphanumeric
fax protocol pass-through g711ulaw
This is the config at IPIPGW:
dial-peer voice 12 voip
incoming called-number [12]...
dtmf-relay h245-alphanumeric
!
dial-peer voice 13 voip
destination-pattern [12]...
session protocol sipv2
session target ipv4:10.2.200.21
dtmf-relay rtp-nte (***I tried rtp-nte digit-drop h245-alp but no success)
codec g711ulaw
!
