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 B-47).
Note that a Trunk Seized Event Report is generated when the switch 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...

Outgoing Call over ISDN Trunk that Results in
an ISDN Progress Message
This section presents the call flow for an outgoing call over an ISDN trunk that 
traverses one or more non-ISDN networks before it reaches its destination. 
Station 4567 initiates an outgoing call to an external destination. Station 4567 has 
Domain Control active and uses the Auto Dial capability to initiate the call
(see Figure B-48).
When a call leaves the ISDN network,...

User Scenarios — User to User Information
Figure B-49 shows a typical distributed call configuration. An ASAI host is 
connected to each of the switches and calls are delivered to either switch. The 
applications running on the ASAI hosts are not connected to each other.

The following call sequences show typical UUI scenarios. Call Sequence 1 shows 
an incoming non-ISDN PRI call to Switch A, delivered to VDN1. VDN1 delivers the 
call to VRU Port1 in VRU Split1. After the caller terminates the VRU session, the 
ASAI host transfers the call to VDN2 for further processing. The ASAI host 
includes UUI in the 3rd Party Make Call used to start the transfer. While the call is 
in VDN2, the call interflows to Switch B. The call is...
