Outgoing Call over Non-ISDN Trunk
This section presents the call flow for an outgoing call over a non-ISDN trunk.
Station 1234 initiates this preview dialing call (see Figure A-16).
Note that a Trunk Seized Event Report is generated when the ECS places the call
over a non-ISDN trunk. Furthermore, no Alerting or Connected Event Reports
follow a Trunk Seized Event Report. The only event report that may be generated
for the destination is a Dropped Event Report.
