Fanvil x4 phones all lost connectivity at once.

[Cytranic]

I have a strange issue, could be a network issue but I figured I'd post here:

I have a client with around 30 Phones fanvils, and 60 3cx clients. PC can grab a DHCP, and 3cx client works fine. However all the fanvil phones can no longer get DHCP addresses. Computers and other devices can get DHCP fine.

Anyone every seen this?

Yes.

I have encountered this issue on Fanvil X5S phones. The problem was network related. Cant remember exactly but it was either switch or cabling. If i remember rightly, moving the port on the switch to another fixed the problem so was probably the switch in this instance.
