We are using Zoiper behind a PBX. Local calls are a 3-digit-number (Zoiper 5, Windows)
For all calls to the outside world we have to dial a leading zero. You can recognize this number simply by their length. When having "contacts" outside we have to create them in Zoiper with the leading zero which makes it harder to import our contacts into zoiper.
I would like to have a Switch in the config where I can say:
* hide leading zero from outside calls, append leading zero to outside calls
* recognize outside calls by length > x digits
