Receiving a Voice over Wi-Fi call on a BlackBerry device

  1. A BlackBerry Mobile Voice System user connects to an organization's Wi-Fi network and authenticates with the BlackBerry MVS.
  2. Using a desk phone, another user within the organization dials the extension number of the BlackBerry MVS user.
  3. The PBX creates a call establishment request and sends it to the MVS Session Manager over a UDP port using a SIP.
  4. The MVS Session Manager filters the request through the recipient's allowed caller list, blocked caller list, and call scheduling setting, and sends the request to the BlackBerry Enterprise Server.
  5. The BlackBerry Enterprise Server compresses and encrypts the call establishment request, and sends it to the BlackBerry device over the Wi-Fi network.
  6. The device decrypts and decompresses the request, and accepts the call.
  7. The BlackBerry MVS user answers the call and voice communication occurs over an RTP connection that the PBX opens between the two endpoints.
