[SR-Users] Rtpengine?

Hello and thank you for your response.  I was going on something I read that said =>

“Getting rtp_engine to work with the standard kamailio.cfg is to simply add
at the top of the NATMANAGE route so it will handle all rtp regardless of
source being natted (in your config in the NAT router.”

Obviously, this is not correct.

It's not enough to install rtpproxy/rtpengine and start it. You need to call rtpengine functions from kamailio.cfg for every SIP packet with SDP so media will be routed "thru Kamailio".

To make it easier, I recommend to begin with rtpproxy, not rtpengine. Default kamailio.cfg contains everything you need to proxy media flow by rtpproxy, just enable WITH_NAT parameter.

HI All,

I am not sure if I understand it correctly but I thought that I could use rtpengine to redirect media packets.  My current SIP flow is =>
Softphone=>Kamailio=>Asterisk=>Kamailio=>Softphone, and Media flows from is Asterisk<=>softphone. But I don’t want Media to flow this way.
That is, I do not want Asterisk and the Softphone to be aware of each other. I would like the Media to go through Kamailio just like SIP packets do.
I installed rtpengine and it starts and runs with no errors.  I even see traffic with the call is made but media traffic still flows from softphone<=>asterisk.
