This sounds a bit broken: if the client advertises the payload type of
96, thats what it will have in the generated RTP packets, so I don't
really see a valid reason for doing that. Unless the client is really
broken and advertises a ptype of 96, but sends the packets using 101.
Anyhow, in order to do that, you can use the subst_body() function in
the textops module:

Hi,
I have an opensips 2.4 cluster using rtpproxy nodes.
I'm troubleshooting some DTMF issue and have a requirement to change the
inbound INVITE SDP payload from:
a=rtpmap:96 telephone-event/8000
to
a=rtpmap:101 telephone-event/8000
in the outbound INVITE SDP.
How could this mapping/conversion be achieved with my opensips/rtpproxy
setup?
Thank you!
