No outgoing audio except onhold music

[luisdin]

Hello,
we have a 3CX installation on a Windows 10 machine sitting behind a FritzBox. The Fritzbox is configured to let the right ports through but I could not get ports 9000 - 10000 through, only 9000 to 9256. Please tell me if this could solve the problem. On our desks we use 3 x Grandstream Gxp1610 ip telephones.
After hours of configuring, everything works how it should, except audio doesn´t go out of the network. This is not including the onhold music when pausing a call. I find that a little bit confusing and I can´t find the reason why this is. It would be great If you could take a look at the support files.

Thanks and best wishes.
Luis Dinnebier

@luisdin Sorry, I must have skipped over that part. Also note you can change a setting in your Fritz!Box under Home Network > Network > YourPbxMachine to "Always assign this network device the same IPv4 address" so you can keep your DHCP mode intact and also ensure the PBX IP remains the same and avoid any issues in the future.
