Good question. I believe that application level keep alives are generally relied upon in Asterisk's TCP/TLS code. Essentially, a '\r\n\r\n' is sent over the TCP socket every so often to verify/ensure connectivity. Do you have the variable keep_alive_interval set in the [global] section of your pjsip.conf? The value you set it to in seconds is the interval at which it sends a keep alive message over the socket. -- Matthew Fredrickson Digium, Inc. | Engineering Manager 445 Jan Davis Drive NW - Huntsville, AL 35806 - USA -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-dev mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-dev
