-> About SIP: the traffic does not "jump" at a random port, it is -> another type of traffic that you see afterwards, it's the RTP stream. OK!, Thank you. I understand. -> SIP is used only for signaling a session hence the name Session -> Initiation Protocol. The SIP messages contain the IP Address + -> Port where the RTP flow will appear. The RTP might not have the -> same IP address as the SIP destination. If you want to -> prioritize SIP and RTP you can use your own SIP Proxy (i'm using -> SER from www.iptel.org) with somekind of gateway (RTPPROXY may -> be just enough for an end user). Ok, thank you. I'm newbie with VoIP . AFAIK , Ser is a router. But I need to priorize SIP traffic on my (very)custom router linux.2.4.28. There is a way to integrate openSer with it ? best regards andres _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
