I have a CUBE running 15.0(1r)M1. ISP is SIP coming and SIP out to CUCM 8.x.
When I run debug DTMF at the router, I see the digits being pressed. So Im assuming they are coming, but are they coming in the correct format such as 2833, Im not sure. If they are not standard, they will probably no relay correctly to CUCM.
SCCP--CUCM--3rd party SIP end point works fine with DTMF.. so I know its not CUCM. (I think).
My Dial-peers seem to have everything they need from the CUBE to CUCM:
dial-peer voice 200 voip
rtp payload-type nte 120
session protocol sipv2
session target ipv4:x.x.x.x
I configured a transcoder at the router, registered it with CUCM, added it the MRG to the SIP trunk in case for some odd reason the DTMFs needed to be transcoded, no luck. Tried MTP on/off on the trunk, no luck.
Am I missing something really easy here or ???
