n Service/Reason. The example gives the access code and name of the
target dialing service for this rule. If the rule’s action was
Stop
, this
column would list the reason for stopping.
n Notes. Comments that you enter when you create the rule.
A routing service can have many different routing rules. The routing service
attempts to match the number dialed to each routing rule until it reaches the end
of the routing rules or finds a rule that tells it to stop processing the number. If one
or more valid dialing services are found, the routing service attempts to route the
call through the first one found. If all trunks on the first dialing service are busy,
the routing service tries other valid dialing services in the order that they were
found until the call is placed or all valid dialing services have been tried.
Before the routing service passes the number to a dialing service, it modifies the
number according to the pattern specified in
New digits (the number is
unchanged if
New digits matches Digits dialed). The dialing service applies any
prefixes, suffixes, and dialing exceptions (see pages 8-11, 8-14, and 8-22) to the
modified number before the call is placed.
How you can use routing services
By setting up multiple dialing services and using a routing service, you could do
any of the following:
n Set up dialing services to roll over automatically. Set up multiple
routing rules that match the same type of number on the same schedule,
but route to different dialing services. The routing service identifies all
routing rules that match a phone number until it either encounters a stop
rule for that phone number or reaches the end of the routing rules. If all
trunks on the first rule’s target dialing service are busy, the second rule’s
target dialing service is tried, and so on until the call is placed.
n Route local calls and long-distance calls to different trunks. Write
routing rules that identify local calls and route them to dialing services
that offer the lowest cost for local calls. Write another routing rule that
identifies long-distance numbers and routes them to the trunks that offer
the lowest price for long distance.
n Route long-distance calls over an Internet gateway to be made as
local calls from a remote Strata CS Server.
You are in the New York
office. Your company also has an office in Boston. Your New York users
make many calls to the Boston area code (617). You would set up an
Internet-to-Phone Number dialing service named Call Through Boston
that routes calls over the Strata CS Server in Boston. You would then
create a routing rule that matches numbers with the 617 area code
(1617Nxxxxxx) and routes the calls to the Call Through Boston dialing
service.
