Antivirus Firewall rules on client

[dvdg518]

We switched from on-prem to hosted yesterday.
Since then, I cannot hear any voice and vice versa.
If I dial out, I can hear the phone ringing, but no audio when it comes to voice.
If I disable the Enhanced Firewall on my Antivirus, voice starts working.
I added some "allow all" rules, but that doesn't fix it.
Has anything changed with Workstation firewall rules with moving from on-prem to hosted 3CX?

My guess is that your firewall treats external traffic differently than it does internal traffic. The fact is that turning off the firewall fixes the problem and that is your answer. Nothing has changed.

For the Windows client, you should exclude the 3CX folders from anti-virus scanning, but my guess is that your firewall is scanning the data traffic and blocking the audio stream. I would call your antivirus company.
