No audio on inbound and outbound calls

[Frank86]

We are using 3CX with a Spectrum PRI as the primary provider (which works fine) and Flowroute for a few DIDs. The Flowroute DIDs do not have any audio on inbound or outbound calls. Flowroute is configured as a SIP trunk exactly as other 3CX instances we have (where it s the primary SIP provider). We have a Fortigate firewall, and the firewall checker passes all tests. Any suggestions?

• 3CX Version, Enterprise Annual 18 update 4 (build 965)
• Server OS, Windows server 2019 standard
• Is the 3CX Server Hosted and where? Locally
• Provisioning Method: Local
• Trunk Provider or Gateway Make/Model - Flowroute
• Has the Firewall Checker passed: YES
• Are custom Phone Templates being used: NO

Problem fixed. We had to disable NAT on 3CX port forwarding rules.
