Switchvox - Telephony Cards
Table of Contents
The Telephony Cards tools let you scan for and configure new telephony hardware in the Switchvox server. You can also delete hardware. If hardware has not been detected, make sure all cards are installed properly and that the card you are using is supported. See the Digium web site for installation instructions.
Hardware Devices
Each device connected to the Switchvox server is listed under Hardware Devices. To configure a listed device, click Configure for that device. To delete a listed device, click Delete for that device, then verify the deletion request. Devices are listed with Card Type, Device Type, Device Name, Spans (the logical groupings of channels), and Total Channels.
If you have added new hardware, Switchvox detects it when you start the server. If you have deleted a device and want Switchvox to detect it again, click Scan for New Devices. Switchvox detects the telephony hardware and includes it in the Hardware Devices list.
Hardware Country Settings
If you need to change the country in which your Switchvox server is located, select it from the drop down menu, then click Save Country. This setting also sets the call-progress tone scheme that determines the tones sent to your callers.
NOTE: Specifying the country your PBX is located in may adjust analog line impedance and analog signaling tones. This can remedy problems, such as echo, that your phone system could have.
WARNING: Changing this setting will restart your phone system. Any current phone calls will be dropped and any agents logged in to call queues will be logged out.
Hardware Echo Cancellation
This option disables the hardware’s echo cancellation so all echo cancellation is handled by Switchvox.
WARNING: Changing this setting will restart your phone system. Any current phone calls will be dropped and any agents logged in to call queues will be logged out.
For details about those settings, see “Advanced Options” in the Channel Groups article.
Echo Reduction for Analog Lines
This tool allows Switchvox to run a series of tests, after which it calibrates the analog lines to the results in order to reduce the echo on your analog lines when you click Run Echo Reduction Tool. Click Remove Echo Reduction Settings to revert the settings back to their default values.
We recommend running the Echo Reduction Tool if you move lines to other ports, or add new lines.
NOTE: Running this tool causes your system to go offline for approximately two minutes per analog line. Any current phone calls are dropped, and any agents logged in to call queues are logged out.
