# Recorded Announcement Device (RAD) - Description

A Recorded Announcement Device (RAD) is customer-supplied equipment that connects to the system by an ONS, ONS CLASS/CLIP, or OPS line card. (RADs can also be a software-based product such as the Mitel Intelligent Queue which runs on an external server and connects to the MiVoice Business through an IP port. For more information about Intelligent Queue, see Customer Interaction Solutions on the Document Center web site.)

ONS/OPS RADs are activated by a ringing voltage supplied by the system. The primary function of a RAD is to supply messages to incoming calls. This feature is beneficial to companies that want to supply a general first level and a specific second level announcement for individual departments. Each RAD requires a port, a directory number, and its own Class of Service. The number of RADs in a system depends upon the number of announcements required by the customer.

When the RAD detects ringing (supplied by the system to the RAD's Tip and Ring leads) it closes the loop to signal that it has answered. Once the message is played, the RAD clears down and opens the loop. Up to 50 callers can listen to one RAD at the same time. Any caller routed to a busy RAD is camped-on until the recording is finished. When it clears down the RAD is seized and all camped-on callers receive the announcement. All calls maintain their position in the incoming queue, either while listening to the RAD or while queued for its service.

NOTES

- RADs can be shared between hunt groups (agents). This is beneficial to a company that supplies a general first level announcement, and a specific second level for individual departments.

- You cannot interconnect RAD devices.

- You cannot tenant RAD devices.

- SIP RADs are not supported.
