Cisco Cisco Unified MeetingPlace Audio Server Maintenance Manual

With direct access, ports are assigned to a particular service type. For 
example, ports 1–3 to scheduling; and 6–12 to meetings. The number that 
users dial determines which ports they access, and thus which service they 
receive.

When MeetingPlace does not receive dialed number information, the default 
port access type assigned to a call is the type assigned in the Ports topic 
(Configure tab) to the port that is handling the call. If your system does not 
receive dialed number information, you may want to map out the connections 
between MeetingPlace and the telephone network. Then, either decide which 
access type to assign to each line or group of lines that connects to 
MeetingPlace, or choose to use all ports universally with combined access.

If users cannot access a particular service, you can reconfigure the number of 
ports assigned to each MeetingPlace service using the Ports topic.

If you assign an individual port to a port group, you do not have to 

re-enter data that is already provided for the port group.

You can configure MeetingPlace ports to allow or disallow outdialing. Make 
sure that the trunk is configured in MeetingPlace the same way your 
telephony provider has configured it (it can either make outgoing calls or 
cannot make outgoing calls). MeetingPlace can block certain numbers and 
dialing patterns system-wide, by group, or by individual user. Call blocking is 
controlled by an internal MeetingPlace table. Contact your MeetingPlace 
support representative to configure this table.
