Hello! I went through your letters and start as following:
------------------------------------------------------- r...@ubuntu:/home/yeti/rtpproxy# /etc/init.d/kamailio restart Restarting kamailio: kamailioloading modules under /usr/local/lib/kamailio/modules_k/:/usr/local/lib/kamailio/modules/ Listening on udp: 192.168.124.158:5060 udp: FEC0:0:0:0:0:0:0:2:5060 tcp: 192.168.124.158:5060 tcp: FEC0:0:0:0:0:0:0:2:5060 Aliases: tcp: ubuntu:5060 udp: ubuntu:5060 r...@ubuntu:/home/yeti/rtpproxy# kamctl restart INFO: Stopping Kamailio : INFO: stopped INFO: Starting Kamailio : INFO: started (pid: 7597) r...@ubuntu:/home/yeti/rtpproxy# rtpproxy restart ------------------------------------------------------- So I guess everything is starting fine. The users can register and call each other. Their data are in the mysql database`s location table. I put this into the kamailio.cfg file: -------------------------------------------------------- # RTPProxy control route[RTPPROXY] { #!ifdef WITH_NAT if (is_method("BYE")) { unforce_rtp_proxy(); } else if (is_method("INVITE")) { if (af == inet) { if ( $(rU{s.substr,0,1}) == "6") { force_rtp_proxy("ie"); } else { force_rtp_proxy("ee"); } } else { if ( $(rU{s.substr,0,1}) == "4") { force_rtp_proxy("ei"); } else { force_rtp_proxy("ii"); } } } else if (is_method("200OK")) { if (af == inet) { if ( $(rU{s.substr,0,1}) == "6") { force_rtp_proxy("ei"); } else { force_rtp_proxy("ee"); } } else { if ( $(rU{s.substr,0,1}) == "4") { force_rtp_proxy("ie"); } else { force_rtp_proxy("ii"); } } } if (!has_totag()) add_rr_param(";nat=yes"); #!endif return; } ---------------------------------------------------------- But, unfortunately there is no RTP traffic yet. :( What do you thing guys, what can be the problem?

When you call force_rtp_proxy() then you have to provide the i/e flags to tell rtpproxy how it should bridge the call. Therefore you need to know for every call: - is the caller IPv4 or IPv6? - is the callee IPv4 or IPv6? Finding out the protocol version of the caller is rather easy: if (af == inet) { # caller ipv4 ... } else { # caller ipv6 ... } But finding out if the callee is v4 or v6 is difficult. Actually it may even be that the callee is registered with 2 clients at the same time - one using v4 and v6. As far as I know this multi-registration scenario can not be handled currently - only single-registrations or multi-registrations which use the same protocol version are supported. Anyway - there are several approaches how to detect the IP version of the callee. - fixed mapping: for example if you know that all usernames starting with 1 are IPv4 clients, and all usernames starting with 2 are IPv6 clients, then you can detect the callee's protocol version manually, e.g: if ( $(rU{s.substr,0,1}) == "1") { # callee ipv4 ... } else { # callee ipv6 ... } - check destination URI if it contains a IPv4 or IPv6 address, e.g. use http://www.kamailio.org/dokuwiki/doku.php/transformations:devel#resubst_expression to test if $dd contains '.' which would indicate a ipv4 address. - use dedicated location tables > (Because it uses them, for instance here: if (method == "REGISTER") > { if (af == inet) { save("location-inet4"); } else if (af == inet6) > { save("location-inet6");...) > > If I do not have to use it, I do not need to merge it with my > kamailio.cfg file, the steps I have to do are: install rtpproxy, > start it with the appropriate parameters and set the forcing in the > kamailio.cfg file?! The more I think about it I prefer the approach with separated location tables. It should be rather easy to integrate the 2 location tables into your existing config. regards Klaus _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
