Forwarding Calls Over Centrex Or Pbx Trunks; Using Routing Lists - Toshiba STRATA CS Communication Server Release 6 User Manual

Forwarding calls over Centrex or PBX trunks

If your company has trunk lines that are connected by Centrex lines, an external PBX, an ISDN
line with the 2B Channel Transfer feature, or a Strata CS IP Gateway, you can use the
Centrex/PBX transfer feature to economize Strata CS's trunk use.
If properly configured by your administrator, this feature can transfer or forward calls to external
numbers with consuming any Strata CS trunk lines. It works by telling the provider of the call
(the PBX or phone company) to transfer the call on Strata CS's behalf. Without this feature, two
trunk lines are consumed for the duration of the call (one for the incoming call, and one for the
outgoing call).
You can check
add a routing list action. If this option is checked, Strata CS attempts to signal to the call provider
to transfer the call on behalf of Strata CS. Incoming calls on other trunks that don't support this
feature are routed to the forwarding number in the usual way, using a second trunk.
Note:
Forwarding calls with this method avoids tying up extra trunks. However, when a call is
routed out, Strata CS loses control of it and cannot send it to subsequent actions on the user's
routing list. For example, after transfer using Centrex or PBX, a call cannot go to voice mail.

Using routing lists________________________________________

A routing list is a series of phone numbers that Strata CS dials when calls for you arrive. If you
do not answer at one location, Strata CS proceeds to the next. For example, you can set up a
routing list that tries you at your desk, then at your home, and finally at your mobile phone.
A routing list also contains a final action that determines what happens if no one answers.
Usually the caller is sent to your voice mail, but you can specify other final actions. For example,
you can transfer calls to another extension, put callers on hold and try the series of numbers
again, or hang up. You can specify a different final action for when you're on the phone vs. when
you're away from your desk. For example, if your phone is busy you can play a voice mail
greeting such as "I'm sorry I'm on the phone, please leave a message and I'll return your call as
soon as possible."
You can create as many routing lists as you want and make any one of them the active routing
list at any time.
Routing lists for individual callers
By using call rules, you can have Strata CS use a specific routing list for a specific caller or
group of callers. For example, you can have a routing list for important customers that includes
trying your mobile phone and another routing list for everyone else that only rings your
extension. See
