Dear Community Team,
One of the customer is facing issues on 3CX call system after upgrading to new firewall PA-3220 recently. It was Forcepoint Firewall used by the customer earlier and working fine.
Note: 3CX is a software-based private branch exchange based on the SIP standard.
I would need any expert suggestions ASAP.
