No, you can enable responding to them, but not sending them (tcp_crlf_ping = yes). However you could enable tcp level keepalives and on linux you can tune the intervals, e.g.: tcp_keepalive = yes tcp_keepidle = 60 tcp_keepintvl = 10 tcp_keepcnt = 3 Andrei _______________________________________________ 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
