Method B
a. Right-click the existing Node Number. An option box appears.
b. Select Change Node Number. A window appears prompting for the type of device to
include.
c. Select Local Node or Remote Node, and then click Next. The list of nodes appears.
(You can view a list by selecting List or view details by selecting Details.)
d. Select the node, then click Finish. The selection appears as the Node Number.
CO Provides Progress Tones
(BRI/PRI-equipped modules only) When the System provides local ringback, some central
offices [local exchanges], particularly in Europe, take too long to send the System the connect
message when a call is received. When the CO connects a call too slowly, the user can answer
before the caller is on the line, causing the caller to miss the greeting (such as “Welcome to
Mitel. How may I help you?”). If this flag is enabled, the System does not provide local ringback.
Instead, the System connects the call to the line and the caller hears CO ringback. That way,
when the called party answers, the calling party is already on the line. In the default state, the
flag is disabled.
To change the CO Provides Progress Tones setting:
1. Select the current Value and then place a check mark in the box by selecting it. To
remove the check, select the box again.
2. Press ENTER or select another field to save the change.
Connect On Call Proceeding
(PRI-equipped modules only) This flag affects outgoing Primary Rate ISDN calls. If it is enabled,
the system will connect the B-channel as soon as the Call Proceeding message is received
from the CO interface. Some CO interfaces, especially SS7 interfaces, do not send progress
indicators when they are playing tones or announcements on the B-channel. They play the tone
or announcement prior to sending the progress message, after the call proceeding. In this case,
if the flag is disabled, the user experiences audio clipping. If the flag is enabled, the channel is
opened when the call proceeding message is received and the system does not have to wait for
a progress indicator (indicating alerting, busy, reorder tones or announcements).
IMPORTANT
If you change the ISDN Switch Type to Private Networking, the
system automatically places the trunks in the first available node
trunk group. For more information about node trunk groups, refer
to the Mitel 5000 Features and Programming Guide, part number
580.8006. If you change to any other ISDN Switch Type option, all
of the trunks are moved to the “Unused” trunk group.
IMPORTANT
This flag should be enabled for PRI spans that are used for placing
outgoing calls from another node (for example, Node 2 uses ARS
to place outgoing calls using the PRI span on Node 1). If it is not
enabled, some of the calls from Node 2 may not go out to the pub-
lic network properly. It is recommended that you enable this flag for
all nodes in a system.
