No, RTPProxy shall also work fine. However, you have to shift all packets to userspace - Mediaproxy doesn't do so. That fact alone should be a great performance advantage. Mediaproxy's architecture is really well done and it allows you to scale far (even if for most setups a single host would suffice). I didn't follow RTPProxy development for a long time, I'm pretty sure there have also been improvements. And: Mediaproxy is not the right tool when you are trying to create some multihomed ALG/SBC- solution, involving private IP addresses. Mediaproy must run on a public IP address.

Re: [OpenSIPS-Users] T38 and changing media port for T38 SDP
Holy shit (pardon my French and excitement), I just ran through the install of MediaProxy on my development server and it all works! All my initial testing works. IT JUST WORKS. What a great piece of software! I was initially put off by the difficult install of MediaProxy and all the hype around RTPProxy being written in C but I can tell you I spent a lot of time trying to get RTPProxy working... And for a long time it was working until I brought on my new T38 Fax server and stuff just didn't work in any consistent and logical fashion. I've been beating my head against a wall for a week. MediaProxy works, RTPProxy doesn't work. Simple as that. Thank you! - Julian On Thu, Jul 15, 2010 at 9:03 PM, Saúl Ibarra Corretgé wrote: > Hi, > >> You mean 'Now all corner cases'?

Re: [OpenSIPS-Users] T38 and changing media port for T38 SDP
Yeah, I am having way too many issues with RTPProxy and the re-invite port changing. It's an absolute nightmare. Everything works fine when the UA doesn't change media port but when it does, it's really inconsistent. Sometimes it works, sometimes it doesn't work. I think I'm going to try out MediaProxy. MediaProxy is able to detect the changing media port? - Julian On Tue, Jul 6, 2010 at 9:19 PM, Adrian Georgescu wrote: > > On Jul 7, 2010, at 12:27 AM, Julian Yap wrote: > >> Hi All, >> >> I managed to get it working by adding a whole lot of debugging and a >> whole lot of rtpproxy_offer() and rtpproxy_answer(). >> >> Now I need to clean up my config because it's a total mess. >> > > You may want to try use mediaproxy if you do not like the mess.

I'm having problems with a T38 UA which changes port when negotiating T38 media. All the other UA's I've encountered thus far use the same RTP port throughout. I'm also using RTPProxy. In the final 200 OK SDP, the UA changes media port from 49200 to 49152 but this changeover isn't detected and the media is sent back to port 49200 so the call then fails to negotiate T38 properly.

Re: [OpenSIPS-Users] T38 and changing media port for T38 SDP
Hi Pavel, Yeah, in my example, the media port is changed on the T38 reinvite. Isn't RTPProxy meant to handle this port change? - Julian 2010/7/3 Pavel Eremin : > you may change and control content of SDP body by module "textops".

Re: [OpenSIPS-Users] T38 and changing media port for T38 SDP
you may change and control content of SDP body by module "textops". So, if port is change you may change it back or log it or smth else... i use it when Broadworks change media port for G711 to 0...

[OpenSIPS-Users] T38 and changing media port for T38 SDP
Any help greatly appreciated! I'm having problems with a T38 UA which changes port when negotiating T38 media. All the other UA's I've encountered thus far use the same RTP port throughout. I'm also using RTPProxy. In the final 200 OK SDP, the UA changes media port from 49200 to 49152 but this changeover isn't detected and the media is sent back to port 49200 so the call then fails to negotiate T38 properly. Not sure how to log the port changes to further debug this issue as well. Here is the flow: | UA | OpenSIPS | T38 GW | | INVITE SDP ( g711U) | | |(5060) --> (5060) | | | 100 Trying| | | |(5060) <-- (5060) | | | | INVITE SDP ( g711U) | | |(5060) --> (5060) | | | 100 Trying| | | |(5060) <-- (5060) | | | 180 Ringing SDP ( g711U) | | |(5060) <-- (5060) | | | 200 OK SDP ( g711U) | | |(5060) <-- (5060) | | | RTP (g711U) | | |(11392) <-- (14110) | | RTP (g711U) | | |(49200) <-- (10878) | | | 180 Ringing SDP ( g711U) | | |(5060) <-- (5060) | | | RTP (g711U) | | |(49200) --> (10878) | | | | RTP (g711U) | | |(11392) --> (14110) | | 200 OK SDP ( g711U) | | |(5060) <-- (5060) | | | ACK | | | |(5060) --> (5060) | | | RTP (g711U) | | |(49200) --> (10878) | | | RTP (g711U) | | |(49200) <-- (10878) | | | | 200 OK SDP ( g711U) | | |(5060) <-- (5060) | | | RTP (g711U) | | |(11392) --> (14110) | | | ACK | | | |(5060) --> (5060) | | 200 OK SDP ( g711U) | | |(5060) <-- (5060) | | | ACK | | | |(5060) --> (5060) | | | RTP (g711U) | | |(49200) --> (10878) | | | RTP (g711U) | | |(49200) <-- (10878) | | | | ACK | | | |(5060) --> (5060) | | | INVITE SDP ( t38) | | |(5060) <-- (5060) | | INVITE SDP ( t38) | | |(5060) <-- (5060) | | | 200 OK SDP ( t38) | | |(5060) --> (5060) | | This is where it sends the 200 OK with a different media port. - Julian ___ Users mailing list Users@lists.opensips.org http://lists.opensips.org/cgi-bin/mailman/listinfo/users
