Shared Parking - Randomly Dropping Calls

[Sean Bray]

Specs: 3CX Hosted, On-site SBC
Trunk: Voiceflex
Handsets: Fanvil X4U

My customer keeps reporting an issue with Shared Parking that I am unable to replicate or find much information in the Logs for.

Reception picks up phone > places the call into Shared Parking > Phones User to inform them they have someone waiting in Shared Parking > User picks up from Share Parking. All done through BLFs.
Now the issue they report is that randomly when the user goes to pick up the Shared Parking it causes the incomming caller to drop off as if the call had been ended. According to the Reporting logs it just shows that the user had terminated the call shortly after picking the user up out of Parking.


I have tried for ages to replicate the issue but cannot get it to trigger myself, yet the customer reports it happening multiple times a day. I can turn on Verbose logging but that will mean leaving it running for days and creating huge Log files. Since the user started having the problem they also stopped using the Shared Parking so getting more logs in a nightmare.

Checked Parking setup and its fully correct:



Anyone have any idea what could be causing this or where to look to diagnose this issue? Any help appreciated!
Thanks,
Sean

Turn on verbose logging and review the log files, you shouldnt have any trouble if the server is adequate. Does the trunk have support reinvites on or off? Is the firewall checker passing.

Thanks,
Checked and the Firewall is passing and support Re-invite is currently Disabled on the trunk.


Convinced them to start using Share Parking again so I can get verbose on and pick it out the logs. Will update this Post next week when I can pick out the logs incase it helps anyone else. Previously with "Low" Enabled on the logs it shows the User instantly terminating the call.
