84CHAPTER 6: USING THE VCX USER INTERFACE
You can also configure and enable call forwarding through your phone’s
Telephone User Interface (TUI). See Call Forwarding.
You can use the VCX User Interface to set:
■How long (in seconds) your telephone rings before the system forwards unanswered calls
■Where you want your call to be forwarded
■The condition (or conditions) that result in the system forwarding a call:
■Ring No Answer — Redirect incoming calls to another destination when your phone rings for a configured time period (the default is 20 seconds).
■Busy Line
■All Calls — Redirect incoming calls to another destination unconditionally. Use this feature when you plan to be away from your phone for an extended period of time. Also referred to as Call Forward Universal.
■Fall Back — Return forwarded calls to your call coverage point if the forwarding destination does not answer. When you enable this Call Forward, Fall Back to Coverage feature, a forwarded call that is not answered at the forwarding destination falls back to your extension's coverage. This call coverage point must be either voice mail or Auto Attendant (the call cannot fall back to another extension or to no coverage; see Configuring a Call Coverage Point).
For example, a call to extension A gets forwarded to extension B if extension A is busy. Extension A has also enabled the Fall Back option. Extension A receives a call that gets forwarded to extension B. However, extension B is also busy. Instead of sending the call to extension B's coverage point or call forwarding destination, VCX returns the call to extension A's voice mail or Auto Attendant.
You can configure the Call Forward, Fall Back to Coverage feature through the VCX User Interface only. This feature cannot be configured through the Telephone User Interface.
