Moving a call from a BlackBerry device to a one-time number using Voice over Mobile

  1. During a Voice over Mobile call on a BlackBerry device, a BlackBerry Mobile Voice System user presses the Menu key, clicks Move Call, and clicks One-Time Number. On the Options screen, the user clicks or types a one-time number to move the call to.
  2. The BlackBerry MVS Client creates a call move request, which includes the one-time number to move the call to. One of the following events occurs:
    • If the user is in a wireless coverage area where data services are not available, the BlackBerry MVS Client uses DTMF tones to create the request, and sends it to the MVS Session Manager over the wireless network.
    • If the user is in a wireless coverage area where data services are available, the BlackBerry MVS Client compresses and encrypts the request, and sends it to the BlackBerry Enterprise Server over the wireless network. The BlackBerry Enterprise Server decrypts and decompresses the request, and sends it to the MVS BlackBerry Enterprise Server Connector. The MVS BlackBerry Enterprise Server Connector sends the request to the MVS Session Manager.
  3. The MVS Session Manager sends the request to the PBX to establish a call to the one-time number over the SIP line.
  4. The PBX determines that the one-time number is external to the organization and rings the one-time number over the PSTN.
  5. The user answers the call at the external phone.
  6. The PBX verifies through SIP messaging with the MVS Session Manager that the call was answered.
  7. The MVS Session Manager ends the SIP trunk call leg with the BlackBerry device, and ends the call on the BlackBerry device. The user continues the call on the one-time number.
