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

  1. A BlackBerry Mobile Voice System user connects to a Wi-Fi network and authenticates with the BlackBerry MVS. On the BlackBerry device, the user presses the Menu key, clicks Move Call, and clicks One-Time Number. On the Options screen, the user clicks or types a phone number to move the call to.
  2. The device starts a call move request. The device compresses, encrypts, and sends the request to the BlackBerry Enterprise Server over the Wi-Fi network.
  3. The BlackBerry Enterprise Server decrypts, decompresses, and sends the request to the MVS BlackBerry Enterprise Server Connector over a TCP connection.
  4. The MVS BlackBerry Enterprise Server Connector sends the request to the MVS Session Manager.
  5. The MVS Session Manager sends the request using SIP to the PBX over a UDP port.
  6. The PBX determines that the one-time number is an external number and rings the one-time number over the PSTN.
  7. The recipient answers the call at the external phone and voice communication occurs over an RTP connection that is open between the device and PBX.
