For number 918558897592 I only see you (your freeswitch dialplan app) hanging up the call: 2016-09-09 10:54:19.892289 [NOTICE] switch_core_state_machine.c:315 sofia/external/+918558897592 has executed the last dialplan instruction, hanging up. So I guess I would look at the dialplan. There is also a lot of retransmissions between your freeswitch and your asterisk gateway, which is maybe not related to your problem but it doesn’t appear to me like you have a quality network situation. The log is a bit difficult to read, because it doesn’t seem to contain a full example of an INVITE - OK and then call drop. Your asterisk is also requiring session timers (with a 15 min expiry) so another thing to validate is that those session refreshes are actually being sent. Can you get a simpler log showing an incoming call from setup until it drops?

Does the caller suddenly stop sending audio, but no SIP packet to indicate the end of the session. Therefore FreeSWITCH would time out (on receipt of no audio) and terminate. 2. Does the caller or FreeSWITCH send a termination (in the form of a BYE) to the other party? If this is the case, look at the logs for something that provoked it.

One problem that I am facing is frequent call drops of the connected callers. My program has a logic of redialing a caller in case of disconnection, if the caller is not reachable due to some reason the redial happens three times. I am maintaining sufficient balance to keep 22 channels in parallel and also for the duration of calls. One thing that I am observing which I am not sure to be the cause is when I increased the redial trial to five times, the frequency of call drops increased. Is the dialing attempt count should be taken care for the balance maintenance or there is some other cause ? The Freeswitch logs are of type - CALL REJECTED, USER BUSY Regards, Deepika _________________________________________________________________________ Professional FreeSWITCH Consulting Services: consulting@freeswitch.org <mailto:consulting@freeswitch.org> http://www.freeswitchsolutions.com <http://www.freeswitchsolutions.com/> Official FreeSWITCH Sites http://www.freeswitch.org <http://www.freeswitch.org/> http://confluence.freeswitch.org <http://confluence.freeswitch.org/> http://www.cluecon.com <http://www.cluecon.com/> FreeSWITCH-users mailing list FreeSWITCH-users@lists.freeswitch.org <mailto:FreeSWITCH-users@lists.freeswitch.org> http://lists.freeswitch.org/mailman/listinfo/freeswitch-users <http://lists.freeswitch.org/mailman/listinfo/freeswitch-users> UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users <http://lists.freeswitch.org/mailman/options/freeswitch-users> http://www.freeswitch.org <http://www.freeswitch.org/> -- All the best, Ben Cropley 07539 366 905 _________________________________________________________________________ Professional FreeSWITCH Consulting Services: consulting@freeswitch.org <mailto:consulting@freeswitch.org> http://www.freeswitchsolutions.com <http://www.freeswitchsolutions.com/> Official FreeSWITCH Sites http://www.freeswitch.org <http://www.freeswitch.org/> http://confluence.freeswitch.org <http://confluence.freeswitch.org/> http://www.cluecon.com <http://www.cluecon.com/> FreeSWITCH-users mailing list FreeSWITCH-users@lists.freeswitch.org <mailto:FreeSWITCH-users@lists.freeswitch.org> http://lists.freeswitch.org/mailman/listinfo/freeswitch-users <http://lists.freeswitch.org/mailman/listinfo/freeswitch-users> UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users <http://lists.freeswitch.org/mailman/options/freeswitch-users> http://www.freeswitch.org <http://www.freeswitch.org/> _________________________________________________________________________ Professional FreeSWITCH Consulting Services: consulting@freeswitch.org http://www.freeswitchsolutions.com Official FreeSWITCH Sites http://www.freeswitch.org http://confluence.freeswitch.org http://www.cluecon.com 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
