[OpenSIPS-Users] B2B Opensips + RTPEngine

[amel.guesmi at sofrecom.com]

Hello all,

Thank you for your help, the rtp_relay_engage function worked very well and we can now have the SDP changed correctly when the frames are passing the B2B opensips.

                ## Handle rtp_relay
                  $rtp_relay = "co";
                  $rtp_relay_peer = "co";
                  $rtp_relay_engage("rtpengine");

We are meeting a new problem : we have two interfaces on our Opensips, one external and one internal and we have to change the SDP engage with each interface.
We want the opensips to change SDP with RTP internal when we're going from external to internal (in UAS mode), and with external in the other way (in UAC mode).

  +    ----   INVITE (SDP RTP1) ---->       B2B         ------ INVITE (SDP RTPint) --->   Client
RTP1                                  RTPext   RTPint                                     RTPcl


       <---   200OK  (SDP RTPext) ----       B2B        <------ 200OK  (SDP RTPcl) ---   Client




Thanks for your help.

Hi Amel,

With 3.3 you can use the this https://opensips.org/docs/modules/3.3.x/rtp_relay.html#func_rtp_relay_engage - the engage will take care of all sequential (in the b2b scenario) insertion of the rtp relay you use.

Hi,

Which OpenSIPS version do you use? some have auto rtp engaging support via the rtp_relay module.

Hello Community,

We are trying to set up an Opensips with RTPEngine in a B2B configuration to handle media processing. There is no scenario for the B2B we're trying to implement, we're just using the topology « «top hiding » !

However, regardless of our configuration, the SDP of the INVITE and 200 OK packets is not modified to include the RTPEngine IP address and port

How should the RTPEngine be configured in the Opensips.cfg or which function(s) should be called to achieve this?
