Even when you use line pools, it is possible that a line pool will be unavailable for outgoing
traffic. To alleviate this, you can determine overflow paths for any routes that you designate.
Refer to
"Using multiple routes and overflow routing" on page 348
about overflow routing.
•
Incoming lines can be assigned to telephones as individual lines or through target lines,
depending on the type of trunk supplied from the central office (CO). Incoming lines do not
need to have an appearance on the telephone. Target lines are for incoming calls only.
Two-way single lines, such as analog lines, allow the user to make an outgoing call by
pressing the (idle) assigned line button or, if the line is part of a line pool, by entering a line
pool access code or destination code to access the line pool. These lines can also be redirected
on a per-trunk basis or from the telephone by using FEATURE 84.
•
PRI lines are always configured into line pools. These lines require a destination code for
outgoing calls. Incoming calls use target line assignments.
•
Voice over IP (VoIP) trunks use the data network to provide line service in and out of the
system. VoIP trunk configuration is described in the IP Telephony Configuration Guide. VoIP
trunks use target lines for incoming calls, and require line pool codes or destination codes for
outgoing calls.
•
You can assign a line a maximum of 93 times.
