We have a local v2 FreePBX server that has been running for a year or so with Polycom 335 phones. Today a handful of phones can call out but can’t hear any audio, but most of the phones are still working.
If you call another local extension from one of the non-working phones, they can hear you, but you can’t hear them.
If you call one of the non-working extensions from a working local extension, you get a busy signal.
The phones that aren’t working show up as offline in the End Point Configuration Manager.
I’ve rebooted FreePBX server, the Hyper-V host, all the network switches, created and assigned new extensions to the non-working phones, factory reset the phones. No change
Does that make any sense? Anything else to try? It’s like the phones are only half-registering…
