4. Chapter 4: Configuring simulator with PSTN Manager

Using PSTN Manager is the only way of conguring the simulator.

Any changes that you make in PSTN Manager do not take an effect until you save the conguration to PSTN

simulator. Some of the changes can be applied "on the y" and some requires a reboot of the simulator. PSTN

Manger will determine if the Reboot is required and automatically reboot the simulator if needed.

Please note that all established calls will be lost if simulator is rebooted.

You can also save your current conguration to a le on the disk by accessing a

"Main Menu -> File-> Save Cong" interface.

PSTN Manager is a set of conguration Tabs for Global (applicable to all ports) and Local (port specic)

parameters. The actual set of parameters is based on rmware version and rmware feature set installed and

activated on a particular PSTN simulator.

4.1 Replicating conguration among FXS ports

You can easily replicate changes made on a single FXS port To: or From: particular FXS port by using a

"Copy conguration" button on each FXS port conguration tab.

You can copy conguration from the current port to all FXS ports or a particular FXS port number or you can

copy conguration from any FXS port number to a current FXS port.

Please note that Phone numbers and Caller ID information will not be copied as a part of this process.
