# Defining Alternate Server addresses

The Alternate Server address feature allows you to specify alternate registration servers, if the main registration server, defined on the telephony login screen, is not available.

Note

This feature is independent of the Alternate Gatekeeper function available in Communication Manager. The Alternate Gatekeeper List (AGL) is computed by Communication Manager at each registration and is provided to the endpoint during a successful Registration, Access, Security (RAS) process. The Alternate Server feature, on the other hand, allows a successful RAS session to be set up to begin with.

## Prerequisites

Obtain the alternate server addresses from your administrator.

1. On the top bar, click System Options > System Settings.
2. In the System Settings dialog box, click Alternate Server List.
3. In the Alternate Server List panel:
   1. Click Add.
   2. In the blank field, type the IP address or FQDN of the alternate server.

      To add more servers to the list, repeat the sub-steps a and b.

   3. In the Maximum attempts of each server field, specify the number of attempts the system make to connect to each server before switching to the next defined server.
4. Click OK to save the settings.
