SBC failed to register and calls drop

[joemsith16]

The SBC fails to register randomly causing any call open at the time to drop. The SBC then registers OK.

Where can I find the reason the SBC is failing to register?

Is the WAN of your 3CX PBX IP dynamic or static?

Thanks for the quick reply,

The first check would be to check the router stats at the SBC side to see the uptime.

Then increase 3CX logging on the PBX to verbose and try and replicate.

failing that, increase logging on the SBC via the PBX, reprovision and then pull the log off the SBC and look in there.

the log should be located on the SBC in /var/log/3cxsbc/3cxsbc.log - im not sure if the location for windows. But, you didnt specify your SBC.

You can also try to update your SBC to 16.2.24 which is our latest beta and a close release candidate.
