No I Tried O2 and Orange. However, it does seem to work when you call the
(Orange) mobile number voipcheap is presenting. Doesn't work when you call
another Orange mobile.

I have a hunch it is something to do with mobile networks expecting a mobile
number to the GSM spec, whereas landline carriers may be happy with UK
landline format or GSM format. If I used the format +447.... with voip
cheap verification process AND was able to put it in the ATA in the same
format as an Auth ID / Internet Number, I have a hunch it would work.
However, my FritzBox doesn't allow any non-numeric in Internet Number, so I
can't test this.
