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.
Setup:-
- 3CX server has been hosted outside with public IP directly.
- Users are behind the PA firewall using application to connect 3CX and make and receive calls.
- In PA, Many to one NAT configured to access 3CX server.
Issues:-
- Users are unable to hear the audio from incoming sometime.
- Calls are getting disconnected randomly.
Action:-
- Allowed any application and any ports without any security profiles, but still the issues are occurring.
- Disabled ALG in SIP, but same.
I would need any expert suggestions ASAP.
Thanks
Ananth

It was resolved after increasing session timeout in service ports.
Thanks,
Ananth
