SCCP DTMF Out of band to in-band conversion

[tgi9babyjo]

Hi,

is there anyway to convert sccp out of band dtmf to in-band without rfc2833?

I've got media termination point configured to convert out of band DTMF to In-band DTMF and then send the digits code to SIP device

The issue is the SIP provider does not accept RFC2388 and we have to convert it to in-band DTMF but not RFC2833.

I think you're stuck here. It appears that CUBE will receive and convert SIP INFO events into in-band audio tones; however, neither CUCM or IOS support sending digits this way. It's time to find a new ITSP; not supporting RFC2833 is an indication of amateur hour - or worse, legacy equipment - IMO.
