Fallback Alias

TANDBERG VIDEO COMMUNICATIONS SERVER ADMINISTRATOR GUIDE

Overview		Configuration		Example Usage

It is possible for the VCS to receive a call that is destined for it but which does not specify an alias. This could be for one of the following reasons:

•the caller has dialled the IP address of the VCS directly

•the caller has dialled the domain name without giving an alias as a prefix

•the caller has dialled the IP address or domain name of the VCS prefixed by the

VCS’s system name as an alias.

Normally such calls would be disconnected. However, the VCS allows you to specify an alias to which all such calls should be routed. This alias is known as the Fallback Alias.

To configure the Fallback Alias:

•VCS Configuration > Calls.

You will be taken to the Calls page.

•xConfiguration Call Services Fallback Alias

You may wish to configure your Fallback Alias to be that of your receptionist, so that all calls that do not specify an alias will still be answered personally and can then be redirected appropriately.

For example, Example Inc. has the domain of example.com. The endpoint at reception has the alias reception@example.com.

They configure their VCS with a fallback alias of reception@example.com. This means that any calls made directly to example.com (i.e. without being prefixed by an alias), are forwarded to reception@example.com, where the receptionist answers the call and directs it appropriately.

Some endpoints do not allow users to enter an alias and an IP address to which the call should be placed.

Fallback alias

Enter the alias to which you want to forward all calls that do not already specify an alias.

If no fallback alias is configured, calls that do not specify an alias will be disconnected.
