10. Calls Across Multiple Switches
This section presents several scenarios for calls routed, transferred, or 
conferenced across switches. Figure B-32 shows the VDNs, vectors, splits, and 
extensions for the following scenarios. Each switch has its own ASAI link, but 
ASAI links are not shown in the figure.
NOTE:
Section 15 gives examples of calls between switches using UUI.
The trunk groups that are connected between Switch A and Switch B in this 
scenario should...

External Call to VDN, Answered by Station and
Transferred to a VDN on Another Switch
This scenario shows the call flow for an incoming ISDN PRI call to VDN 5678 
answered by extension 4555 in ACD split 3333 (see Figure B-33). The agent at 
extension 4555 manually transfers the call to VDN 1222 in Switch B. Extension 
1567 in ACD split 1444 answers the call at Switch B.
The scenario shows the agent at extension 4555 completing the transfer...
