Sorry,
What meant to try to get across was, if I dial the international access code then the country code and then the number i require, the dialing patterns rule the strip the appropriate numbers and append other appropriate number to suit the format that the VOIP provider requires to allow the call to go though.
I.E. I dial 0011 44 123 4567890 the system should modify that and send 00 44 123 4567890
Is SAIL/SME able to do this?
