Intercom Calls
Intercom calls allow extensions to communicate with each other internally. They can
be made to a single extension, group, or the Base Unit can page all extensions.
There are two types of intercom calls between Cordless Handsets: one is normal
intercom which can be made without the presence of the Base Unit if there are no
calls held by the Cordless Handset; the other is a Base Unit assisted intercom which is
made when there are calls held by the Base Unit. Base Unit assisted intercom is used
to set up a conference call (Please refer to Three-Way Conference Calls for details).
Making an Intercom Call
An intercom call can be made to a specific extension, or an Extension Group, or all
extensions (Base Unit only). If an intercom call is made to an Extension Group or
all extensions, the first extension to answer will be connected. Intercom paging will
time out after 30 seconds if there is no answer and the display will show “Paging
timeout” for a few seconds.
