IP Line Description, Installation and Maintenance

Note: There are no feature keys on the IP Phone 2001.

The feature key labels for each IP Phonee are stored in the Call Server’s

database. When the Call Server performs an EDD, the feature key labels are

saved to the database. The feature key label information is retrieved from the

file into memory during the sysload of the Call Server. When the system

performs an INI or sysload, feature key label changes performed by users

between the last EDD and the INI or sysload are lost.

When the IP Phone registers with the Call Server, the Call Server looks up the

feature key label in the memory, based on the TN of the IP Phone. If the labels

are found, they are sent to the IP Phone when the key map download occurs.

If the labels are not found, the Call Server sends out the key number strings

or key functions.

For more information about programmable line (DN)/feature keys

(self-labeled), refer to IP Phones: Description, Installation, and Operation

(553-3001-368).

Private Zone configuration

Private Zones are available for the CS 1000 and Meridian 1 systems.

Lack of DSP resources

DSP resources for each customer are placed in one common pool. A DSP

channel is allocated to an IP-to-circuit-switched call based on a round-robin

searching algorithm within the pool.
