Bridged Call Appearance

A user can press the Bridged Appearance button on the telephone and join a conference call only if no more than five parties are on the call.

Call Vectoring

A vector directory number (VDN) can be included as a party in a conference call only after vector processing terminates for that call. Vector processing terminates, for example, after a successful route-to command.

Trunk-to-Trunk Transfer

If Trunk-to-Trunk Transfer is disabled on the Feature-Related System-Parameters screen, and the attendant releases from a conference call that involves only trunk conferees, the system disconnects the trunks.

When a user of a BRI, digital, or hybrid multifunction telephone dials enough digits to route a call that might otherwise be routed differently if the user dials additional digits, the telephone does not recognize the Conference or the Transfer buttons. For the system to recognize the Conference or the Transfer buttons, the user must either dial the number again after 3 seconds or dial the pound key (#) at the end of the dialed string at the end of the dialed string. The system identifies this action to route the call and not wait for the additional digits. The system then completes the call.

Attendant conferencing might not operate properly if the central office (CO) does not provide answer supervision. In this case, you must set the Answer Supervision Timeout and the Outgoing End of Dial fields to the same nonzero number and the Receive Answer Supervision field to n.

If the CO provides answer supervision, you can set the Answer Supervision Timeout field to 0 and the Receive Answer Supervision field to y.
