E.164: +39 052 05243 XX (two digits' number range)
I am facing a external phone mask issue from CM --- VG (Italy ISDN BRI ..... that is showing the wrong outgoing phone mask ... even I tried to fill the external phone mask as "+3905205243XX / 05205243XX / 5205243XX / 43XX / 05243XX / 4325 (exact match) " ... All external phone mask showed the wrong calling ID as outside "05205243" ..... I don't know why? Is it the variable number range on the ISDN?, .e.g. that can 05205243 or 05205243X or 05205243XX (the number range can 0 - 2)? If yes, then how can I make the external phone mask on CM?
