  • Method and apparatus for using a B-answer signal to prevent a voice announcement in a group call
    Patent number: 6405051
    Abstract: A technique for preventing voice announcements in a group call is provided. If any voice activity precedes a B-answer signal on a call to a party, that party is not added to the group call. This approach guarantees that no voice announcements will be added to the group call. With this approach, all subscribers are allowed to use voice mail systems, but subscribers currently forwarding messages to a voice mail system will not be connected to group calls.

  • Method and apparatus for using a MS tone to prevent a voice announcement in a group call
    Patent number: 6154645
    Abstract: A technique for preventing voice announcements in a group call is provided. A mobile station is configured to generate an MS tone in response to receiving an individual call from a group controller. The MS tone identifies to the group controller that the mobile station has been reached. Upon receiving and detecting the MS tone, the group controller adds the mobile station to the group call. This approach guarantees that no voice announcements will be added to the group call. With this approach, all subscribers are allowed to use voice mail systems, but the subscribers currently forwarding messages to voice mail will not be connected to group calls.
