3CX V15 Incoming calls Failing

[Andy Veal]

Hello,

Recently our incoming calls are starting to fail more and more and the only way to resolve this is by restarting the PBX server.

Nothing has changed for a while. no config settings on the SIP or any sec settings.

I see this in the logs at around the time of the failures

SIP Server/Call Manager ID: 12294
Call or Registration to 0249987766@(Ln.10000@NetSIP) has failed. 103.26.**.4 replied: 486 Busy Here; from IP:103...4:5060
11/05/2019 11:11:46 AM

and also this:

Extension 999 is unregistered, removed contact: sip:[email protected]:5483;rinstance=cf8f2e630783d1bc

Extension MakeCall is unregistered, removed contact: sip:[email protected]:5483;rinstance=c4796e00e34aca60

Any clues or suggestions as we are seeing this more and more.

Cheers

So you said incoming calls failed, but you showed a log of a failed outgoing call.... You might also want to provide the info outlined here:

Hi Andy, please use the above link to provide detailed info about the system.

Some of those messages are not errors, they are normal depending on what is happening.

Hi, This seems to be another one of those strange 3CX issues, the only thing I did was run a Firewall Check 2 nights ago and since then, no issues.
I got some more feedback from the users and what was happening is that the calls were coming through but were silent.
will re-post If I find anything further.
