Well, it's not working.

I need conversion in opposite way. As my provider requires in-band
DTMF and SCCP phones provides only out-of-band DTMF then I need
conversion out-of-band into in-band.

#show sccp | inc inband
Supported Codec: inband-dtmf to rfc2833 conversion, Maximum
Packetization Period: 30

I was looking for some sort of command to do this in opposite way but
without luck.
