After configuring the zone-based digit manipulation (step 1 and step 2)
and specialized route (step 3), the route must be associated with the ESN
Special Number. The main office ESN Special Number configuration is
based on new digits inserted by zone-based digit manipulation. The digits
are processed based on the Access Code, AC1 or AC2, that was dialed.
For off-net calls the following should be considered:

If all calls that have undergone Zone-based digit manipulation are to be
routed by the NRS, one SPN must be provisioned for each call type to
route calls to the NRS based on the ZDP.
If some calls are to be routed by the NRS, and others by the main office
Call Server, multiple SPN should be provisioned to route calls based on
the ZDP value and one or more dialed digits. Each SPN can then use
a different RLI if required.
For example, assume ZDP = 101. It is possible to provision multiple
SPN (1011, 1012, 1013, 1014, 1015, 1016, 1017, 1018, 1019, and
1010) to route calls based on the ZDP value plus the first dialed digit.
However, it may not be necessary to provision all SPN combinations.
For example, if calls dialed with a first digit of 3 after the Access Code
are invalid, then SPN 1013 does not need to be provisioned.
