With a bridged line, the VCX User Interface Selective Ringing feature allows you to
change the default ring tone to one of 27 ring tones, delay the ring for a specified
number of seconds, or silence the ringer and only allow the telephone to flash.
The bridged telephone is sometimes referred to as the primary phone. The telephone
receiving bridged calls is sometimes referred to as the secondary phone.
A bridged extension is typically used by an administrative assistant (the secondary
phone) to accept calls for one or more managers (primary phones). Or one manager
(primary phone) may be monitored by multiple assistants (secondary phones). The
primary telephone and the secondary telephone (or phones) can be located at different
sites.
Bridging an extension requires three steps:
1) On the telephone whose extension you want to bridge (for example, extension
1000):
s
access the Bridge Permissions tabbed page.
t
receive a bridged call and click Add.
The bridged telephone can identify up to five telephone numbers to bridge with, but
the number of extensions it can actually bridge is determined by the maximum number
of contacts that the system administrator has set up for the phone, which may be
fewer than four.
If you bridge a telephone that is a remote phone, that remote telephone will not appear
in the VCX User Interface Bridged Phones list, but does appear in the administrator's
Bridged Phones list.
2) On the telephone that will receive a bridged call (in this example, extension
1001):
u
access the Button Mappings tabbed page.
v
Appearance (SA) button (either SA 4, SA 5, or both buttons) and click Save.
You should not bridge an extension to a Basic telephone (Models 2101 or 3101)
because these phones have no programmable buttons. Therefore, a Basic telephone
has no way of distinguishing a call to its extension and a bridged call.
3) For the bridged line settings to take effect, the telephone must retrieve the new
settings from the VCX server. By default, phones check the VCX server for new information every
60 minutes (the telephone registration interval). To retrieve bridged line settings, you can use one
of the following options:
Wait for the telephone registration interval to expire (60 minutes or less, depending
on when the last registration occurred).
