My (limited) understanding is that IAX sends all call control and RTP to port 4569. Thus, a busy pipe can adversely affect timing if the single thread reading from the socket can't process the packets fast enough. Whether this manifests itself as dropped packets or jitter or whatever is beyond my experience. I've never had a client complain, but most of my traffic is within the same cabinet. -- Thanks in advance, ------------------------------------------------------------------------- Steve Edwards [email protected] Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000 _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2009 - October 13 - 15 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
