Details on RPM Call Processes
On the incoming call management of the customer profile, the following sequence occurs to determine
if a call is answered:
1. The incoming DNIS is mapped to a DNIS group; if there is no incoming DNIS number, or the DNIS
number provided does not match any configured DNIS group, the DNIS group default is used.
2. The mapped DNIS group is checked against configured call discriminator profiles to confirm if this
DNIS group/call-type combination is disallowed. If there is a match, the call is immediately
rejected.
3. Once a DNIS group or a default DNIS group is identified, the customer profile associated with that
DNIS group and the call type (from the bearer capability for ISDN call, statically configured for
CAS calls) is selected. If there is no corresponding customer profile, the call is rejected.
4. The customer profile includes a session limit value and an overflow limit value. If these thresholds
are not met, the call is then assigned the appropriate resource defined in the customer profile. If the
thresholds are met, the call is rejected.
Table 42 Call-Treatment Table
Event Call-Treatment Option Results
Customer profile not
found
No answer (default) The caller receives rings until the switch
eventually times out. Implies that the NAS
was appropriate, but resources were
unavailable. The caller should try later.
Busy The switch drops the call from the NAS and
sends a busy signal back to the caller. The call
is rejected based on not matching a DNIS
group/call type and customer profile. Can be
used to immediately reject the call and free up
the circuit.
Customer profile limits
exceeded
Busy The switch drops the call from the NAS and
sends a busy signal back to the caller.
NAS resource not
available
Channel not available
(default)
The switch sends the call to the next channel
in the trunk group. The call can be answered,
but the NAS does not have any available
resources in the resource groups. Allows the
switch to try additional channels until it gets
to a different NAS in the same trunk group
that has the available resources.
Busy The switch drops the call from the NAS and
sends a busy signal back to the caller. Can be
used when the trunk group does not span
additional NASes.
Call discrimination match No answer The caller receives rings until the switch
eventually times out.
