3CX does not have any reply after it receives bye message.

[Grace Liu]

Hello everyone,

When we connect 3CX server with one sip trunk(3CX does not support) through IP to IP, 3CX server cannot terminate the incoming call after 3CX server receives bye message, what are the possible reasons?
In the 3CX capture, the sip account provide keeps sending bye message, but 3CX does not have any reply.


We will appreciate it if anybody has any suggestions.

Thanks
Regards
Grace

Hi Grace.
It will be good to see the logs of the actual 3CX System at this point, and what the System is doing there.
If this is a supported SIP trunk, you can open the ticket with us so that we could review the logs.

Thank you

@OlegR_3CX Thanks for your reply.

Sorry, the sip trunk is not supported by 3CX, and it is our first time to test it too.

Could you please help us check the capture here?

Thanks
Regards
Grace

It's not really clear why the System does not answer, and the logs of the 3CX System needs to be checked (you could have the system in verbose and use Binlog viewer tool).
As you know, if the trunk is not supported, we won't be able to advise and investigate the issue.

In the capture, we can find the bye message from sip trunk side:


But in the log tool, there is not the corresponding bye message:


Does anybody have any suggestions?

Thanks

Hi Grace.
I could only advise not to filter anything in binlog, and to check the sequence before BYE message and while the message if any errors etc.
