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.

It was resolved after increasing session timeout in service ports.

If you are decrypting traffic, do not decrypt this traffic. Also on the security policy that is going to the 3CX, dont apply any security profiles.

Hi @OtakarKlier ,
Thanks for your comment. BTW, We don't have any decryption policies configured and no security profiles are not configured.
