Intersystem Calling 2
Table 2–26, page 2-97 illustrates dialing and recipient screen displays for calling
among extensions in Scenario 5. Note the following facts about intersystem
calling in this scenario:
■ The full 5-digit DEFINITY ECS or DEFINITY ProLogix Solutions extension
numbers display at recipient extensions on the MERLIN LEGEND
Communications Systems.
■ The PassageWay Telephony Services application on System N displays
UDP-routed calls as inside calls.
■ PassageWay Telephony Services clients on System N cannot receive
screen pop with the original caller information on a call that is transferred
from System A. Instead, they receive information about the transfer
originator. When such a transfer is made, the originator reviews the PRI-
ANI information on his or her digital display telephone. Then the originator
makes a transfer with consultation to a specific PassageWay Telephony
Services client extension, telling the user at the extension what the calling
party digits are. This allows the System N technician to bring up the
customer information manually on his or her screen.
■ MERLIN LEGEND Communications System users dial the full 5-digit
DEFINITY ECS or DEFINITY ProLogix Solutions extension numbers, but
the systems perform routing based on the first four digits.
In systems earlier than Release 6.0, Version 11, when a MERLIN LEGEND
Communications System user calls an extension on System A, it is
important to dial the fifth digit of the DEFINITY ECS or DEFINITY ProLogix
Solutions extension number within two seconds of dialing the fourth digit,
for correct routing.
For Release 6.0, Version 11 and later systems, programming the number
of dialed digits as 5 makes this restriction unnecessary and speeds call
setup time.
