Zoom Licensed Phone Calls Dropping

Hello there,

Thank you for contacting the Sophos Community.

You would need to create exceptions for Zoom or create a separate Firewall Rule for the Destination Networks for Zoom; here is a RR on the exclusion list for zoom.

Still Facing the Same Issue. while getting the incoming phone call, there is silent or suddenly call ended or breaking the voice or not able to hear anything. again if we dial the same number (outgoing) then its working. every time from different numbers same issue.
