IPFire Fritzbox SIP Call

Security
1

Hello fellow forum members.

I registered here because I can’t find a solution to my problem. We’re using an IPFire firewall connected to a Fritz!Box.

I’ve installed a SIP client on my Windows PC.

Now I have the problem that I can dial a number, and the call goes through to the other party. But unfortunately, no audio is transmitted.

Do you perhaps have a solution? I’m completely stuck :frowning:

Thank you very much.
Micha

You need to forward the rtp ports to the fritzbox.

Usually fritzboxes uses udp 7078 to 7110 for rtp
