Call-by-Call Service Table 4
When a call is placed on a Call-by-Call B-channel group, a s pecific service is
selected. The selected service depends on the match betwe en the dialed digits
and the table entries. A service must be specified; otherwise the entry is ignored.
The Call-by-Call table can contain up to 10 entries. Each entry can contain up to
10 patterns, each with a maximum of eight digits. If a dialed number matches two
patterns, the longer pattern takes precedence. For example, 212555 matches
both 212555 and 212, but the system will match the lon ger pattern. In addition to
patterns, the Call-by-Call table can be used to specify from 0 through 8 digits to be
deleted (the default is 0).
If the last entry in the table is empty (that is, if no pattern is specified), this entry is
used as a default and matches any pattern and type of call.
If ARS (Hybrid/PBX only) is used, ARS selects the route. If the route points to a
Call-by-Call B-Channel group, Call-by-Call service selects the network service.
ARS Call-by-Call service is integrated according to the specified bearer capability
(voice, data, or both) for each feature. In addition, ARS digit deletion/addition m ay
help specify the service selected by the Call-by-Call feature. See “Automatic
Route Selection” on page –363 for mor e information.
