What kind of firewall is it now and was it before? Turn off SIP ALG if there is one (unless it is a PIX/ASA or Fortinet as those are the only two that seem to handle it ok). -----Original Message----- From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Malay Thakershi Sent: Wednesday, October 06, 2010 11:17 AM To: FreeSWITCH Users Help Subject: [Freeswitch-users] Config issue after router/Firewall change We changed firewall our FS server is behind. All off sudden, no voice heard on answered calls. We made sure all rules are ditto as older router/firewall. We even tried opening up everything but result is same. Called Vitelity: they say according to them calls are OK. Please help with you suggestions. _______________________________________________ FreeSWITCH-users mailing list FreeSWITCH-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org
