Primary Rate Interface (PRI) and T1
patterns for the same type of call are permissible in this table; in such a situation,
the feature selects the entry with the longest matching pattern. For example,
based on the entries in
and a voice call with a Called Party Number
(CdPN) of 908957, Entry 1 is selected, not Entry 2. The last entry is used if the
patterns are of equal matching digits.
For each entry, the following can be specified: a set of patterns, the type of call,
the service to use, and the number of digits to delete.
Characteristics and valid entries for the Call-by-Call Services Table are as follows:
■
By default, the patterns are blank, Call Type is Both, Service is blank, and
Delete Digits is 0.
■
There can be up to 10 entries (0 through 9).
■
Each entry can contain up to 10 patterns of up to 8 digits each.
■
The number of digits to delete can be from 0 through 8 (default is 0).
■
The user can use an entry as a default by selecting a Call Type and
Service and not specifying any patterns.
■
If Service is null (not selected), the entry is ignored. Null and No Service
are not equivalent.

Sample Call-by-Call Services Table
Call-by-call service selection closely resembles ARS in reducing costs and
maximizing the benefits derived from limited resources. While ARS selects the
most cost-effective route, call-by-call service selection selects the optimal service
for that particular call. Call-by-call service selection is integrated with ARS by
including the bearer capability of the calling party in its routing decisions. ARS
serves as the main gateway for accessing the call-by-call B-channel group. The
basic calling process for call-by-call service selection with ARS is as follows:
1.
A user dials ARS.
2.
ARS selects the route and, in this case, the route points to a call-by-call
B-channel group.
