Use the Hot Line feature to automatically dial a specific number.
Two-way hotline or hotline two-way is a hotline button where party A can call party B, or party B can call party A. However, Communication Manager has no native function equivalent.
Note:
Note that the destination number for the hotline button must be already configured on the target Communication Manager station.
Because the number is configured on the target Communication Manager station, a user cannot edit the number on a Device Adapter endpoint. Hence, the Hotline two-way number is read-only on the endpoint.
Two-way hotline is created by having two users share bridged appearances of an X-Port, where only these users have this button. The button is labeled as a hotline button, and when the user initiates a call on this button, Device Adapter initiates a call to the extension. As the only other user with this extension as a bridged appearance is the other party in the two-way hotline, that user is rung.
As a result, to the user, the button follows the behavior of the hotline.
User operation:
  • User A and B have a two-way hotline button on their stations.
  • User A presses the hotline button to call user B.
    • Device Adapter seizes a call appearance.
    • The target number is dialed.
    • User B rings and ringback is provided to user A.
  • User B answers the call. Both parties are in a two-way call.
