Unable to use 3CX outside LAN - There is no audio

[JSimao]

Good Afternoon Dears,

My 3CX works fine on my local netork (LAN). The problem is on WAN (Using only internet), i answer and the call is stablished but there is no Audio whe i use #Cx web client and desktop app.

I talked with my network team and asked to open some ports on firewall like 9000-10999; 5060/5061/5090 but it stilss remain.

Can someone help me please?

Best regards

Hello,
Can you run the firewall checker from the management consol (becarful this will hang up the communication).
Give me a screenshot of the results please.

Hello Stevels, i had already showed this errors to my network team and some links on how to set up this on firewall. We use Fortinet. Big deal here is that we have one 3cx instalation with this errors but works fine on WAN using 3cx desktop.
One note: On my mobile it works fine, only web client and desktop that does not work

Thanks

Well, it's not going to work/not configured correctly if the firewall test fails. That thread I link suggested restarting the firewall, and had other tips. The bottom of https://www.3cx.com/docs/fortigate-firewall-configuration/ suggests restarting also.
