V16 Update No Audio

[pds1]

Anyone else lose audio, incoming and outgoing after the upgrade?

Single extension Yealink T48S. No audio, updated firmware, reprovisioned. Calls are going out/coming in.

No audio on the 3cx client either. Makes me think it's something with SIP Trunk (net2Phone) no longer working with 3CX. Anyone else have this issue?

3CX Windows Clients No longer registering either.

Reboot,

if this is onsite make sure your prov link is still working with the new install.

Next
run a new firewall test, check activity log.

Tried that too. Rebooted a few times, ran firewall checker. All looks good. Also added flowroute as another sip trunk. No luck.

Deployed via PBXExpress to Azure.

Firewall checker says they're good.
