ISDN QSIG Call Diversion Notification Enhancements
MCDN Trunk Route Optimization is blocked on MCDN calls due to the
Rerouting method used by QSIG Diversion on No Reply, as far as the original
call being kept by the originating PINX to eventually be restored for further
treatment. This case arises if the diverted-to user activates TRO before
alerting, that is, if Call Forwarded All Calls has been activated against the
diverted-to user.
MCDN Trunk Anti Tromboning (TAT)
As the MCDN Trunk Anti Tromboning feature is activated once the call is
established, there is no interaction between this feature and QSIG Call
Diversion Notification.
ISDN Call Connection Limitations
QSIG Diversion is included in the Call Redirection Threshold, as part of the
ISDN Call Connection Limitations feature.
Timed Reminder Recall
In case of QSIG Diversion on No Reply by the Rerouting method, if the
original call is under Slow Answer Recall Timing, then the new call resulting
from QSIG Diversion is also timed for Slow Answer Recall. This applies if
the new diversion call is over an ETSI QSIG link, or to a local analog
(500/2500) set or Meridian proprietary set, but not to a BRI set.
The timer applied to the new diversion call is the remaining timer of the
original call at the time of diversion.
