You can assign either fixed or scheduled UAP for each Call-by-Call Service Selection trunk group.
•
With a fixed UAP, one plan applies at all times.
•
With a scheduled UAP, different plans can be administered to apply at different times of day and
different days of the week. As many as 6 activation times and associated plans can be assigned for
each day of the week.
You can have anything from a simple fixed UAP to a very flexible UAP with many scheduling options.
You can even start out with no UAP and build one as the need arises.
Incoming call-handling treatment
Call-by-Call Service Selection provides special incoming call-handling treatment for ISDN trunk groups.
An incoming call on an ISDN trunk is handled according to a treatment table administered for the trunk
group. Depending on the platform you use, the table allows for a different number of combinations of call
treatments.
The treatment for an incoming call is selected based on the first 3 columns in the ICHT on the ISDN
Trunk Group screen. When the attributes of an incoming call match these specifications, the call is
treated according to the corresponding following 4 columns. If an incoming call matches more than one
set of specifications, the most restrictive case applies. The following table lists the possible cases from
most restrictive to least restrictive.
Most

Call detail recording
On successful call attempts using ISDN Call-By-Call trunk groups, CDR records the NSF specified by
the call's NSF IE. CDR refers to this information as the ISDN Network Service (INS). The value passed
to CDR is the 3-digit equivalent of NSF IE. NSF information for Facility Type 2 calls (used with
ISDN-Pri Call-by-Call trunk groups) also is recorded if the NSF is available in the incoming SETUP
message.
If an outgoing Call-by-Call Service Selection call uses an interexchange carrier other than the
presubscribed common carrier, CDR records the 3-digit or 4-digit Interexchange Carrier Code (IXC).
CDR may not record the IXC properly if the dialed-code format differs from the US IXC formats.
