- A BlackBerry Mobile Voice System user makes or answers a call on the desk phone. The PBX establishes a connection between the two endpoints and voice communication occurs.
- On the BlackBerry device, the user presses the Send key and then presses the Menu key. If data services are available, the Move Call From Desk menu item appears. The user clicks Move Call From Desk. The user is prompted to place the desk phone on hold.
- On the desk phone, the user places the call on hold.
- The device compresses and encrypts the request, and sends it to the BlackBerry Enterprise Server.
- 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.
- The call leg is established
using one of the following methods:
- The BlackBerry MVS Client uses the wireless voice network to make a call to the PBX. The PBX routes the call to the BlackBerry MVS Session Manager over the SIP trunk using the DID/DDI number.
- The PBX sends the call to the BlackBerry device using the Caller Identification Number of the Telephony Connector. The BlackBerry MVS Client receives a call. The BlackBerry MVS Client sends a verification code request to the MVS Session Manager using DTMF tones. If the ANI in the incoming call is empty, the MVS Session Manager sends a verification code response to the BlackBerry device using DTMF tones.
- The MVS Session Manager, using the SIP line, requests that the PBX move the call to the BlackBerry MVS line.
- The call continues on the BlackBerry device.
