[Serusers] RE: New versions of RTP proxy/nathelper commited

[Kevin Chu]

Hi,

I have a couple questions for rtpproxy/nathelper:

(1) Can rtpproxy/nathelper support calls with multiple media
    sessions (e.g. video conversation between WMs)?
(2) Is there any plan for adding the support for non-symmetric
    RTP UAs like Siemens SCS client in the near future?

Thanks,
Kevin

Hi,

I've just committed major update for rtpproxy/nathelper, which adds 
support for proxying RTCP and also make RTP proxy behave much better for 
non-NATed clients by pre-loading remote addresses[1] of each party from 
the SIP request/reply. Please note that proxy's command protocol has 
been extended to support new functionality, so that you need both new 
rtp proxy and new nathelper (old nathelper will not work with new rtp 
proxy and vice versa). Both of them can be obtained from the ser's cvs 
repository:

http://cvs.berlios.de/cgi-bin/viewcvs.cgi/ser/rtpproxy/
http://cvs.berlios.de/cgi-bin/viewcvs.cgi/ser/sip_router/modules/nathelper/

Please let me know if there are any problems with the new version.

[1] currently only IPv4 addresses can be pre-loaded, though it should be 
trivial to extend proxy, nathelper and command protocol to accomodate 
IPv6 as well. Proxy's core supports IPv4<->IPv4, IPv4<->IPv6 and 
IPv6<->IPv6 relaying already both for RTP and RTCP.
