Zoom Phone & FortiEDR

[SimonDow]

We have been using Zoom Phone system for a few years now and have found it invaluable for all our users especially for the working from home. Last week we have been instructed by our Head Office to install FortiEDR on all company systems, since this installation we have had a very intermittent Zoom Phone service where calls were being made from PC's but there was no ringing tone heard and when the called party answered there was no audio.

After many days of testing the network, checking firewalls, restarting switches we decided to remove the EDR product from some key systems, the problem disappeared! 

Has anyone else had the same or similar issue, and possibly have a solution to get these products to work in harmony with each other?
