IOS sdk not sending BYE

[maria-farooq]

this morning I had a call with @lefty on staging i used ios-sdk, my client name was carol call started around 08:39:34 UTC and lasted more than an hour. i properly clicked on hangup button. here are LoadBalancer logs and RC logs. https://app.box.com/files/0/f/17307973893/ios_sdk_not_sending_bye we can see INVITE from both lefty1 and carol and we only see BYE from lefty1 and not carol

@maria-farooq from the ios logs it seems that a little before you hangup, the periodic registration with Restcomm fails with a Restcomm 503 Service Unavailable:

73:22 4/restcomm-olympus: NOTICE (ssc_sip.mm:2022) REGISTER: 503 Service Unavailable
73:22 4/restcomm-olympus: ERROR (ssc_sip.mm:2031) REGISTER failed: 503 Service Unavailable
73:22 4/restcomm-olympus: NOTICE (RCDevice.m:436) [RCDevice didSignallingError: {
  "NSLocalizedDescription" : "Error connecting to Restcomm: service unavailable"

And after that all signaling towards Restcomm fails, like the attempt to send a BYE:

84:04 4/restcomm-olympus: DEBUG (ssc_sip.mm:1371) UA: BYE to sips:[email protected]

Any idea why Restcomm/LB might have returned that?

@maria-farooq I also checked again your second problematic session, which occurred in our daily meeting yesterday and it appears that ios olympus sends BYE out to Restcomm:

But didn't see a response coming in afterwards. Could you check the server side logs at 14:17:27 UTC, to see if there's anything wrong there?

@atsakiridis i uploaded LB server logs in same box. I could not find BYE from carol any time around 14:17:27 UTC. in these logs you might find another call from carol around 13:33 UTC please ignore that as that was before the daily conference started. thanks Maria
