If a user wants to call number 1588902923, he/she should dial 91588902923. The PBX will strip digit 9 from the dialed number, and call the number 1588902923.
Prepend
Prepend is an optional setting. The prepend will be added to the beginning of a successful match. If the dialed number matches the Pattern, the prepend will be added to the beginning of the number before placing the call.
