I need to dial to PSTN line short dialing strings - 088 and 03. If I make in Outbound call rule - Calls with number with 0 , without r, dialing string 088 not go out, there is information - Call(C:35) is rejected: Destination could not be found. It seems that because extentions are 3-digits lengh the 3cx is searching extention number 088. The dialing string 03 goes correctly to PSTN line. If I make Calls with number with 0, with r ( remove the first digit 0), dialing string 0088 go out , but 003 doesn't go. What to do ? It will work if I make Calls with number with 00 then remove them (rr). But it's not convenient to dial 00 always when want to call to PSTN. Could anybody give advice ?
