I have been using Xnet's Open VFX for over a year now using a Fritzbox Fon WLAN. Last week I added a second VIOP line (to replace a normal Telecom line). Now when one line is in use, I can't call out or receive calls on the second line. The second line does ring but when answered does not connect.
Does anyone know how to fix this? The Xnet Support suggested I may need to open another port? But I am not sure how or were to do this.

You need to use a different port - both lines can't use 5060 which is presumably what you've set.

Thanks for that. Does anyone know how to select another port on a Fritzbox?

I forgot to mention, the Fritzbox sits behind a DSL router.
The following ports are mapped:

MAPPED PORTS
ID Public Port Private Port Port Type Host IP Address
2 80 1234 TCP 10.123.123.123
3 81 1234 TCP 10.123.123.123
6 1720 1234 TCP 10.123.123.123
7 5000 1234 TCP 10.123.123.123

MAPPED PORT RANGES
ID Start Port End Port Port Type Host IP Address
1 1 79 TCP 10.123.123.123
4 82 445 TCP 10.123.123.123
5 1000 1030 TCP 10.123.123.123

Could it be that other ports have to be mapped here?

After hours of trying all sorts of setting I found the problem.
There is a setting in the Fritzbox were you enter the available bandwidth. If this is set to low, Fritzbox will limit the number of simultaneous calls so the quality of the calls are not compromised.
