# Outbound Caller ID Control
Outbound caller ID control provides the ability to dynamically select your outbound number presentation based on a dialled prefix entered before the dialled number on each call.
9 dynamic outbound caller ID numbers can be made available using this feature.
Dial the prefix, followed by the number you wish to dial.
Example: If the prefix is 1 and the number you wish to dial is 0731051xxx.
Dial: 1 0731051xxx.
