Apperance Button Operation: Other Appearance Controls
8.6.11 Twinning
Twinning is a mechanism that allows an user to have their calls alert at two phones. The user's normal phone is referred
to as the primary, the twinned phone as the secondary.
By default only calls alerting on the primary phone's call appearance buttons are twinned. For internal twinning, the
system supports options to allow calls alerting on other types of appearance buttons to also alert at the secondary phone.
These options are set through the User | Twinning section of the system configuration and are Twin Bridge
Appearances, Twin Coverage Appearances and Twin Line Appearances. In all cases they are subject to the
secondary having the ability to indicate additional alerting calls.
Call alerting at the secondary phone ignoring any Ring Delay settings of the appearance button being used at the primary
phone. The only exception is buttons set to No Ring, in which case calls are not twinned.
8.6.12 Busy on Held
For a user who has Busy on Held selected, when they have a call on hold, the system treats them as busy to any
further calls. This feature is intended primarily for analog phone extension users. Within Branch Gateway Manager,
selecting Busy on Held for a user who also has call appearance keys will cause a prompt offering to remove the Busy
on Held selection.
8.6.13 Reserving a Call Appearance Button
Functions such as transferring calls using a Transfer key require the user to have at least one available call appearance
button in order to complete the outgoing call part of the process. However, by default all call appearance button are
available to receive incoming calls at all times. Through the system configuration it is possible to reserve the user's last
call appearance button for making outgoing calls only.
ยท 1400, 1600, 9500 and 9600 Series telephone users can put a call on hold pending transfer if they already have
held calls even if they have no free call appearance button available. See Context Sensitive Transfer .
