Yes it is, if you tell kamailio to rewrite SDP by calling rtpengine functions. During your previous messages I never got the idea you were talking about an uplink/provider interconnect (might be me just skimming your mails). But without a config (of kamailio and rtpengine and a clear network topology) it is not possible to tell what the problem is. The standard config in the kamailio repo does NAT checks before calling rtpengine, if you scrap those conditions it will trigger rtpengine on all calls. signature.asc Description: PGP signature ___ Kamailio (SER) - Users Mailing List sr-users@lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
Re: [SR-Users] Struggling with RTPProxy and RTPEngine
Good morning Daniel, If RTPEngine is on the same server as Kamailio (Asterisk being on another server), and RTP traffic is sent to and from RTPEngine, then the provider only needs to whitelist one IP-Address. I thought with RTPEngine that all RTP traffic would go through it and then it would pass it on to the correct destination. Is this correct?

Re: [SR-Users] Struggling with RTPProxy and RTPEngine
The expectation that the RTP will come from the same place as the signalling does exist in some sclerotic telco interconnects, since big brand SBCs would ordinarily meet this need and big brand SBCs are the only thing sclerotic telcos understand. But I agree that it's an exotic and uncommon requirement, certainly not applicable to anything like end-user UAs or ordinary business SIP devices. -- Sent from mobile.

Re: [SR-Users] Struggling with RTPProxy and RTPEngine
Why would the UAC need to 'whitelist' Asterisk?
Here's an example of an inbound call from Asterisk to a UAC with a sip
proxy in the middle.
Notice how the proxy mangles SDP in the 200 OK reply. Media will flow
directly.
Not saying you shouldn't figure it out how to setup and use rtp proxies,
just that it's not a must in all scenarios, especially when you have a
media gateway such as Asterisk listening on a public interface.

Hello all,
I can't seem to get either RTPProxy or RTPEngine to work correctly. I have
decided to concentrate on RTPEngine because I have read that it works the best.
I am using Asterisk with Kamailio in front. When I make calls, I see RTPEngine
being hit but I continually get the error "Call-ID not found", calls work but
media traffic doesn't go through RTPEngine. I have tried many combination of
the flags but I seem to always get the same error.When I look at the
tcpdump log, I see that the media offer is not on the RTPEngine port. Is there
a common mis-configuration error that can cause this?
I know I can send all my logs and configurations but I really want to try and
resolve this as a learning experience.
