Activating and storing configurations

When a command is issued, it is placed in a temporary storage area where it can be stored or

removed by user operation. To implement a change, that command must be stored in Flash

memory with the activate command and then stored in the configuration file with a commit

command so when the VDR is rebooted it is part of the current configuration. When a sequence

of commands is entered and processed, it changes the values of the affected parameters in a

temporary area, but this does not affect current operation which uses values in the active area.

When you issue the activate command, the new configuration data is moved from the temporary

area to the active area, where it can actually be used. Thus a user can make multiple changes in the

temporary area, for example, using set coding commands, then put them into use with a single

activate command.

Use the activate command only between calls since when it is invoked, it tears down (disrupts)

any calls that are in progress.

Configuration data in the active area is only available while the software platform remains in

operation. If the reset command is issued, or if the platform is manually reset, the active area is

reloaded from the data stored in Flash memory. Data in the active area may be saved to Flash

memory by entering the commit command.

Evaluating call quality

H.323 support includes Call Detail Record (CDR) functionality. CDR records every successful

phone call which is placed through the VDR. Each successful phone call will have one record in

the CDR list. The System Administrator can extract and review detailed records concerning

phone quality and also can access these records for billing purposes.
