I have a couple of PAP2T analogue telephone adapters one of which I use for VoIP access - which works very well.
I have included in the dial plan the entry
09!
to block calls to high cost premium rate numbers starting 09. However I cannot find any information as to what happens if such a number is dialled. Should I get a number unavailable tone, a busy signal, a voice message or what? I have tried formats such as
09!
09x!
09x.!
0906!
the last number - 0906 - being an attempt to block a supposedly complete four digit number even though such numbers do not exist in the UK. At each attempt I just get silence. I know of someone else who is suffering the same problem.
Can anyone tell me what I am doing wrong (if anything) please so that I can get the function to work.
TIA
