Hello, i have configured my 3cx to use a 0 in front of an external call.... so if you would like to call to an external extension you have to dial a 0 in front. i need to do this because of the situation that the hotel use a 3 based extension system and also have internal extension with the same number as some emergency numbers here in austria. my problem now is that this hotel also have internal extension which also used as a emergency number like 122 or 133. also they would like to disable external calls from the guest extension... as they should be allowed to dial to the an emergency number i have added 0122, 0133 and so on to 3cx emergency numbers. the problem is that this numbers will not get over the configured outbound rules > this rule should delete the 0 in front (for an external call) but it doesn't! so the emergency call can not be done!
