Fanvil IP Phone shows unregistered at times

[aslampa]

We have 3CX Phone system V12.5 Std with Fanvil X3S IP Phone. We are getting SIP registration failed in one Fanvil IP phone at times and it is not happening all phones. Restart may helps to fix the problem but it continuous. Hence we would like to have permanent fix for the same. Is there anyway to track this and fix permanently.

Please note that various issues wit Fanvil registration have been fixed in the latest firmware supported by V15.5. So i would recommend upgrading your PBX to V15.5 so you can benefit from these fixes.
