I've recently joined Snap VDSL and received their lovely Fritzbox 7340, and I'm attempting to get my VFX line working with it. (It's an asterisk profile).
I seem to have entered all the settings OK, and can make outgoing calls, but cannot receive incoming calls - the caller simply gets the Phone Number Unavailable message.
The Fritzbox shows that the Telephone Number is up and available, and the strange thing is that MyVFX Xport panel shows registered as well.
I have entered:
Phone number without the leading 0 in the Internet Telephone Number field
username in the User Name field
secret in the Password field
220.127.116.11 in the Registrar field
18.104.22.168 in the Proxy server field (also tried it with this field blank)
tick in Use Internet telephone number for Registration
There are no ports to forward or open as it is all internal to the Fritzbox.
What have I missed?
