Multiple Least Cost Routing - Nortel ICS Install Manual

13. Set AbsorbLength to 1.
The 9 will be absorbed before the number is dialed out to
the network. This means, that when the Night schedule is
chosen, either automatically by time, or manually from a
control telephone, the calls dialed with 91 will dial out to
the long distance network without requiring a special
access code.
To set up multiple alternative routes, refer to the next section,
