AC15 Recall: Transfer from Meridian 1
If Party Z parks the call initiated by Party X (an external caller), then the
AC15 Recall: Transfer cannot be used to call Party Y. Party Z can neither
park, selectively, one member of a split trunk nor park a whole split trunk.
This avoids a recall to an attendant on the recall originating node that would
not be able to send a recall to toggle from one party to another.
AC15 Recall: Transfer from Norstar
Remote access to call park from AC15 TIE trunks is not permitted. It is not
possible to park an AC15 trunk if it has a call on hold. When an AC15 trunk
is parked, it is not allowed to initiate a consultation call.
Access Restrictions
A call can be parked on any DN, regardless of its Class of Service. Access
to a parked call is governed by the same Class of Service limitations for
normal trunk-to-telephone call processing.
