After a large number of users were moved outside the network of the On-Premise 3CX server. Users connection goes down usually 1-2 times a day at random times(although recently suspiciously close to a 9:00 am meeting so more users are on VoIP than usual) for about 5-10 minutes, this affects both the desktop application & grandstream desktop phones.
The firewall where the remote users are located don’t show any type of IPS block in logs. Local 3CX server traffic has a large amount TCP reset-I’s during this time.
