Re: [SR-Users] Is Media Release (signaling only) possible in Kamailio?

Update : I piggy backed Freeswitch to Kamailio and have resolved the issue. No media touching us now. Pros and Cons for doing that I know. But we have it working. Thanks for the dialog.  KD On Wednesday, May 9, 2018, 8:57:49 PM EDT, KamDev Essa wrote: Response

Re: [SR-Users] Is Media Release (signaling only) possible in Kamailio?

Response from the carrier matches your description. Looks like their Inbound carrier is latching but the outbound carrier is not and yes they recommended handling the NAT on my end. That said, whats my options here. Is the native rtpproxy scalable? or is it better to go with a Freeswitch farm

Re: [SR-Users] Is Media Release (signaling only) possible in Kamailio?

Re-read the piece of the article related to "RTP latching": http://blog.csrpswitch.com/server-side-nat-traversal-with-kamailio-the-definitive-guide/ In order for RTP to reach a NAT'd endpoint, all other things being equal, the other party has to do RTP latching. This is true of both inbound and

Re: [SR-Users] Is Media Release (signaling only) possible in Kamailio?

Well then why does Inbound (from carrier to NATed UA) call work. Kam is doing something clever there. Why not when sending the call out.  KD   On Wednesday, May 9, 2018, 4:34:55 PM EDT, Alex Balashov wrote: Oh, the UAs are NAT'd? Yeah, you're going to need

Re: [SR-Users] Is Media Release (signaling only) possible in Kamailio?

Update. I just checked inbound calls using the "rtpproxy clean" cfg.  Inbound calls from Carrier to UA work fine with bidirectional RTP. Its the outbound calls from UA to carrier that have a NAT issue. I am so close :)  KD On Wednesday, May 9, 2018, 4:29:39 PM EDT, KamDev Essa

Oh, the UAs are NAT'd? Yeah, you're going to need something clever in the middle that can do the RTP latching, then. -- Alex -- Sent via mobile, please forgive typos and brevity. ___ Kamailio (SER) - Users Mailing List sr-users@lists.kamailio.org

Re: [SR-Users] Is Media Release (signaling only) possible in Kamailio?

That did not help. sip capture shows NATed SDP being sent to carrier. Obviously carrier will not be able to make head nor tails about it. And carrier SDP sent to UA is perfect as its not NATed. So UA ===> Carrier is fine. Carrier > UA is no RTP.  Does not look like Kam alone can do RTP

Re: [SR-Users] Is Media Release (signaling only) possible in Kamailio?

If I comment out the modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722") as suggested, I do get RTP flowing just in one direction.  From the UA to kam and out to the carrier. I get nothing geting back to the end point. In other words 1 way RTP. Looks like its Kam RTPProxy or bust. KD

Re: [SR-Users] Is Media Release (signaling only) possible in Kamailio?

Correct. So remove all semblance of any RTP proxy and the resulting behaviour will be exactly what you expect. On May 9, 2018 2:13:22 PM EDT, KamDev Essa wrote: >I dont. I want the 2 end points to talk to each other because I am on >AWS with shaky bandwidth stats. It can

Re: [SR-Users] Is Media Release (signaling only) possible in Kamailio?

I dont. I want the 2 end points to talk to each other because I am on AWS with shaky bandwidth stats. It can handle signalingbut not RTP.  However the cfg entry modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722") gives me to believe (not tcdumped RTP ports yet to prove it ) that Kam

Re: [SR-Users] Is Media Release (signaling only) possible in Kamailio?

That depends. Start with a more basic question: why do you need RTP relay in the middle at all? On May 9, 2018 1:54:55 PM EDT, KamDev Essa wrote: >So all calls that kamailio processes using the default cfg file anchor >RTP on the kamailio server? Is it a best architecture

Re: [SR-Users] Is Media Release (signaling only) possible in Kamailio?

So all calls that kamailio processes using the default cfg file anchor RTP on the kamailio server? Is it a best architecture to farm out RTP to Freeswitch? Or is the Kamailio RTP proxy a better gig? KD On Wednesday, May 9, 2018, 1:38:04 PM EDT, Alex Balashov

Re: [SR-Users] Is Media Release (signaling only) possible in Kamailio?

Ironically, nothing. Kamailio doesn't touch the respective parties' SDP unless you invoke an RTP relay (or something else like fix_nated_sdp()). On May 9, 2018 1:03:19 PM EDT, KamDev Essa wrote: >What cfg files changes do I need to make to get Kamailio to be a >signally

[SR-Users] Is Media Release (signaling only) possible in Kamailio?

What cfg files changes do I need to make to get Kamailio to be a signally only server, yet manipulate the SDP part of the INVITE message to allow remote parties to send media to each other? In Freeswitch terms "bypassmedia". KD___ Kamailio (SER) -
