Releasing from Conference Tandem CO Line Connections

This feature enables unattended line-to-line connections for the Strata system, freeing the conferencing analog station or voice mail port for other calls and important tasks. When a tandem connection is set up with a [DN] button, the [DN] button will go idle after releasing from the connection. The [DN] can then be used to make or receive calls from the originating digital telephone.

Standard telephones and/or VM devices can establish tandem analog CO line connections and then release from them without disconnecting the tandem connection in the Strata system. After releasing from a tandem call, reconnecting to the call can be accomplished by dialing an access code. This reconnect feature does not work if one or both of the CO lines are digital.

Whether or not tandem line buttons appear on a telephone, the telephone user can enter the connection and release the line that was connected to the original line or release both lines by pressing the Cancel button.
