Well, its a technical constraint... I have to use SIP INFO.

I use reinvites on my asterisk server, so the PBX is not part of the audio stream. The phone RTP data is directed towards my VOIP gateway device (a standalone T1 to Voip gateway). If I use inband or rfc2833, then asterisk never receives my dtmf, and I cannot use feature codes to transfer a call, record a call, etc.

I use SIP INFO since the SIP data still goes through asterisk. DTMF codes travel through asterisk on the way to the gateway device, so the feature codes still work..

If this feature doesn't exist, I understand... SIP-INFO isn't supposed to make noise. I was just curious if there was a workaround.
