Fanvil X6 BLF status issue

[geelong1]

Hey,

Have a Amazon Lightsail hosted 3CX running the latest (not beta) V16.
Have a bunch of Fanvil X6 handsets all running Firmware 1.10.8 which is the latest 3CX supported release.
all the phone templates are up to date.

The issue we're having is that sometimes when an extension is on a call, the BLF for that extension is not changing from green to red on other extensions.
This is intermittent and cant always be reproduced, but I have seen it happen, the phone system has only been installed for a week and its noticable enough that staff have made some complaints about it.

I have logged in to some of the phones to check that the Cisco Discovery Protocol is turned off - and it is which I saw on another thread here was the root cause of some problems with the Fanvil phones recently.
I also went back and renamed any extensions that had a space in the name - just in case that this special character was causing problems, which is mentioned on the 3CX page about provisioning Fanvil phones.

Any ideas on what else can be done to resolve this issue?

How are the phones connected to the Lightsail instance? Since the information is not provided I'm guessing STUN, and probably without the per phone port forwarding which could potentially cause the issues you are describing. Or it could just be Fanvil.

How are the phones provisioned ?. Are you using stun.

If you are using stun, you need to configure each phone with different ports and setup port forwarding on the firewall protecting the phones.

Another solution, install an SBC server

Sounds like I'm Halfway there,
We're using STUN for provisioning, and each phone has had its ports set up incrementally in 3CX
eg
Extension 1, 5065 / 14000 - 14019
Extension 2, 5066 / 14020 - 14039

However I do not have the phones set up with static IP's in the local network and the specific Local ports forwarded to them too, I'll get that configured today and see if the problem goes away.
Thanks for the info

Static Ip can be manual setup of phone ip, or dhcp reservation. DHCP reservation is best
