Chapter 15: Twinning
Twinning is a process whereby your calls ring on two phones. Twinning is only available if
configured by your system administrator. The system supports several methods of twinning.
Feature Description
Mobile Twinning Mobile twinning allows your calls to ring at both your phone's and at another
phone's number, which can include an external number. If you have been
configured as a mobile twinning user, you can switch the use of mobile
twinning on or off through the phone's menus and can also change the
number to which you are twinned.
Using the phone menus, you can switch use of mobile twinning on/off and
change the destination number for twinned calls.
Fallback Twinning When enabled, this feature redirected your calls to your mobile twinning
number when the system is unable to detect your normal extension
connected to the system. You can use fallback twinning without having to
have mobile twinning switched on.
Internal Twinning This method of twinning twins your normal phone with another internal
phone. Your incoming calls ring on both phones. You can also make your
calls from either extension.
• A typical example for internal twinning would be a user who uses both a
normal desk phone and also needs a mobile phone while moving around
the building.
• Your settings are applied to both phones. Similarly, message waiting
indication and voicemail access from either phone is to your mailbox.
• If both phones are phones that store your contacts and call history on the
system, the contacts and call history on each is the same.
