Nortel Integrated Conference Bridge Service Implementation Guide
The ICB card selects the port for dialing out. The port is available if the 
number of ports reserved for the conference is greater than the number 
of conferees that have joined the conference. When all reserved ports 
are taken, the port can be available, if there are un-reserved ports on 
the ICB card and the port expansion feature is enabled for that 
conference. If all reserved ports are taken and there are no 
unscheduled ports available, the system cannot complete the call.
Note:  When the chairperson dials out to another ICB conference, 
two ports are seized, the dial-out port of the local ICB and the dial-in 
port of the remote ICB. This connection can be terminated only if the 
chairperson drops the dial-out port of the local ICB. However, 
normally the dial-out call is a telephone, so the system only seizes 
one port.
Dial-out Authorization
The Dial-out Authorization feature enables the chairperson to connect 
external parties to the conference when the desired destination number 
is restricted.
This feature uses the Meridian Authorization feature. As such, the 
chairperson must be aware of outdialing restrictions and know the 
authorization access code (Flexible Feature Code – FFC or Special 
Prefix – SPRE on the CS 1000; Auth Access # on the CS 2100/Meridian 
SL-100).
The chairperson must enter the whole string of authorization numbers 
as the example in 
 shows. There are no 
confirmation tones or dial tone in the middle of dialing.
