[OpenSIPS-Users] Force rtpmap:101

Hi everyone

I am getting some INVITE's that are requesting a=rtpmap:100
telephone-event/8000 and some other codecs too which is breaking DTMF.

What I really need to do is to force a=rtpmap:101 telephone-event/8000 in
the replies.
Can anyone tell me how to do this please? I've been looking at the docs but
I'm struggling with this one.

I am using RTPEngine and OpenSIPS 3.0

Many thanks!
Mark.
