Process flow: Adding another party to a call on a BlackBerry device


This diagram shows the elements that are described in the following process flow.

  1. A BlackBerry® Mobile Voice System user dials the extension of Party B to conference the party into an active call with Party A using a BlackBerry device.
  2. The BlackBerry MVS Client sends the code for the ad hoc conference and the destination extension number of Party B to the PBX over the PSTN using DTMF codes.
  3. The PBX sends the DTMF codes to the media gateway.
  4. The media gateway converts the DTMF codes to an RTP packet, and sends the RTP packet to the BlackBerry MVS Call Processor over the LAN.
  5. The BlackBerry MVS Call Processor recognizes the code for the ad hoc conference, places Party A on hold, and creates a SIP call to dial the destination extension number of Party B. The BlackBerry MVS Call Processor sends the SIP call to the BlackBerry MVS Session Manager.
  6. The BlackBerry MVS Session Manager sends the SIP call to the media gateway over the LAN.
  7. The media gateway converts the SIP call to ISDN, and sends the call to the PBX.
  8. The PBX sends the call to the destination extension number.
  9. Party B answers the call and speaks to the user.
  10. The user completes the conference on the BlackBerry device, and all parties can speak with each other.
