I'm running a SIP provider trunk into a CUBE setup (IPIPGW IOS) to a CUCM 6.1

All is working except when users end up in Unity Connection any DTMF's they press are followed by Unity stating "I did not recognize that as a valid entry"

The exact same handler dialer internally works fine... Even the trace from the gateway is fine...

Dial-Peers are as follows....

dial-peer voice 6112 voip

description inbound leg from SIPProvider

rtp payload-type nte 120

session protocol sipv2

incoming called-number 6112

dtmf-relay rtp-nte

codec g711ulaw

fax rate disable


dial-peer voice 7112 voip

description Outbound Leg to CUCM

destination-pattern 6112

session target ipv4:

dtmf-relay h245-alphanumeric

codec g711ulaw

fax rate disable

no vad

And the H245 even sends the right stuff, did I miss something?

Configure the DSP resources to be able to do in-band conversion for dtmf.
