User Guide for the Polycom VVX 1500 Business Media Phone Working with Multiple and Shared Lines
80 Polycom, Inc.
The following figure shows a phone set up with one phone line (2076). Since
one Line Key is taken, there are five keys available that you can assign as
Speed Dial Keys. In this example, five Speed Dial Keys are set up.
Supporting Multiple Line Keys Per Line
Your system administrator can assign each phone line to a single Line Key, or
to multiple Line Keys.
Incoming and outgoing calls for a phone line will be distributed evenly across
all Line Keys that are assigned to the phone line. For example, if you have two
Line Keys set up as 1952, and you have an active call for 1952 on the first
Line Key, an incoming call for 1952 will go to the second Line Key.
Your phone can be set up to have a combination of lines with a single Line Key
and lines with multiple Line Keys.
