transferred station.

How to configure
Call Duration Control can be enabled/disabled for each station for the following cases,
• Call Duration Control for Outgoing (External) calls.
• Call Duration Control for Incoming (External) calls.
• Call Duration Control for Internal calls.
Configuring CDC parameters (such as enabling CDC for different types of calls, defining the CDC timer, assigning
Allowed and Denied lists) forms a table which is called the CDC Table. Decide the CDC table that you should
configure. Each CDC table would appear as shown below:
• Maximum four CDC tables can be programmed.
• One such table can be assigned to the station user.
• All CDC tables are available by default and they satisfy most of the requirements. Hence these tables
can be directly assigned to the stations.
The default CDC Table is configured as follows,
Parameter Value
Internal Call Control Yes/No
Incoming Call Control Yes/No
Outgoing Call Control Yes/No
Allowed List List Number from 0 to 7
Denied List List Number from 0 to 7
