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.

You cannot do this with OpenSIPS, mainly as OpenSIPS has no access to RTP in order to "see" the RFC2833 DTMFs.

I have an OpenSIPS server with trunks to a provider and to a 3rd party and routing calls between the two. The provider sends DTMF as RFC2833 but the 3rd party requires SIP INFO. Somehow I need to translate from RFC2833 to SIP INFO - is this possible?
