Ignore Network Answer Supervision
This field appears only if the Coverage of Calls Redirected Off-Net Enabled field on this screen is y.
CCRON may use a call classifier port to determine whether an off-net coverage or forwarded call has
been answered, discarding other information that may indicate an answered state. However, some
customers pay the operating company to provide network answer supervision on their trunks and desire
that CCRON not discard that information. They may preserve this service by setting this field to n.
On the other hand, beware when you tandem a call over a tie trunk through another media server or
switch node from where it redirects to the public network over non-ISDN facilities. If the trunk on the
far-end node sends a timed answer supervision, that may get tandemed back to the originating node as a
network answer. In such a scenario, the originating media server or switch interprets the call as answered,
leading to some undesirable behavior. To avoid these calls from mistakenly be treated as answered, set
this field to y. An unfortunate consequence is that a short cut-through delay that is inherent to call
classification is introduced when the call is answered.
