After configuring the zone-based digit manipulation (
and
)
and specialized route (
), 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 which 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 SPNs 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 SPNs (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.
•
Be careful when choosing how many dialed digits to include in the
SPN. If one of the dialed digits is included in the SPN (that is, ZDP +
one dialed digit), a maximum of ten SPNs must be configured for each
Branch Office. Similarly if two dialed digits are included in the SPN
