[OpenSIPS-Users] RFC2833 to INFO

[Mark Farmer]

Thanks Bogdan. I was beginning to fear as much but I do need a solution for
this. I will try to explain the problem in more detail.

Our 3rd party is a secure payment gateway and only receives audio following
a SIP RE-INVITE. This is to re-route the audio so that DTMF tones can be
removed. At this point the DTMF is required to be transmitted to the 3rd
party as SIP INFO messages. Once the payment process is complete, there is
another SIP RE-INVITE to switch the audio back to it's original path.

What I have is OpenSIPS & RTPProxy combination but this is a PoC platform
so I can change things. Is there a method to have an RTP proxy instruct
OpenSIPS to generate SIP INFO messages and send them to the 3rd party? It
doesn't matter if we end up with both RFC2833 and SIP INFO - the 3rd party
will just act on the INFO messages.

TIA
Mark.
