Hi, I have configured FreeSwitch and played it by making calls. Every thing went fine. Then I tried to see what happens if network cable is unplugged. Freeswitch shown an error saying ping failed to the gateway and IP address is changed to local system IP. After sometime network cable plugged back in and in another 30 seconds freeswitch has shown it got the IP of gateway and changed back from local IP to gateway IP. After that when I tried to make calls, calls are not going through. Even there is no log displayed in Freeswitch. Please find below the logs... freeswitch@QA360BASExp> 2009-10-28 16:46:13.156250 [WARNING] sofia.c:2814 Ping failed ihub-trunk 2009-10-28 16:46:13.234375 [INFO] mod_sofia.c:3160 IP change detected [192.168.12.10]->[192.168.20.138] []->[] 2009-10-28 16:46:13.265625 [NOTICE] sofia_glue.c:3444 Reload XML [Success] 2009-10-28 16:46:13.265625 [INFO] switch_time.c:661 Timezone reloaded 0 definitions 2009-10-28 16:46:14.156250 [NOTICE] sofia.c:921 Waiting for worker thread 2009-10-28 16:46:14.156250 [NOTICE] sofia_glue.c:3505 deleted gateway ihub-trunk 2009-10-28 16:46:14.156250 [NOTICE] sofia_reg.c:2122 Added gateway 'ihub-trunk' to profile 'TrunkExternal' 2009-10-28 16:46:14.156250 [NOTICE] sofia.c:2767 Started Profile TrunkExternal [sofia_reg_TrunkExternal] 2009-10-28 16:46:14.156250 [ERR] sofia.c:805 Error Creating SIP UA for profile: TrunkExternal 2009-10-28 16:46:14.156250 [NOTICE] sofia_glue.c:3505 deleted gateway ihub-trunk 2009-10-28 16:46:53.234375 [INFO] mod_sofia.c:3160 IP change detected [192.168.20.138]->[192.168.12.10] []->[] 2009-10-28 16:46:53.281250 [NOTICE] sofia_glue.c:3444 Reload XML [Success] 2009-10-2816:46:53.281250 [INFO] switch_time.c:661 Timezone reloaded 0 definitions --After this there were no messages Calls went through if I reload freeswitch. Another surprise thing is I checked for the active ports in the system before and after cable unplugged. Port 5060 disappeared after cable is plugged out. This doesn't display even after cable is plugged back in.
