I remember Mark Snow mentioning at one point that there are certain
transformations around DTMF relay that are not supported in a CUBE environment.
I think this was it.
Have you tried changing the sip config to SIP-Notify with H245-Alpha on the
H.323 side?
Mark Snow, if you're monitoring this thread, could you please pipe up? What
was the "allowed" DTMF relay transformation and what wasn't supported?

Yes, I do. It is transcoding the differents codecs from this call. A simple
hold/unhold works also.
The only problem is related to the DTMF. When I call to the Unity from CME
phone It does not "understand" the DTMF digits.
CME Phone ---h323 (h245-alp) g729---> IPIPGW----SIP(rtp-nte)g711u---->Unity

Do you have a transcoder available and registered on the IPIPGW? This sounds
like an issue where you may be having a supplementary services problem. If I'm
right, you probably can't hold and unhold the call either.

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
!
