Process flow: Moving a call from a BlackBerry device to a desk phone


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

  1. A BlackBerry® Mobile Voice System user selects the option on a BlackBerry device to move a call to a desk phone.
  2. The BlackBerry MVS Client sends the move code 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 Server over the LAN.
  5. The BlackBerry MVS Call Processor recognizes the move code, checks the database for the user's desk phone number, and creates a SIP call to dial the desk phone number. 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 desk phone.
  9. The user answers the call on the desk phone.
  10. The BlackBerry MVS Client ends the call on the BlackBerry device, and the user can continue the call on the desk phone.
