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?

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. -Maxim [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.
