Adding a BlackBerry MVS user configured for PBX-initiated calling to a Voice over Mobile call between another BlackBerry MVS user and an external user
- A BlackBerry Mobile Voice System user, Party A, is on a Voice over Mobile call with an external user, Party B.
- Party A presses the Menu key on the BlackBerry device, clicks Add Participant, and dials the number of another BlackBerry MVS user, Party C.
- The BlackBerry MVS Client creates a hold request. The MVS Session Manager places the SIP line call leg into a hold state through the PBX.
- The MVS Session Manager uses the SIP line interface to request that the PBX establish another call leg to the number of Party C.
-
The PBX determines that the number is internal to the organization and sends a new call request to the MVS Session Manager.
- The MVS Session Manager determines the call is PBX-initiated and uses the SIP trunk interface to request that the PBX ring the number of Party C.
-
The MVS Session Manager connects the two call legs.
- When Party C answers the call, Party A presses the Menu key and clicks Join Conference.
- The BlackBerry MVS Client sends a join request to the MVS Session Manager.
- The MVS Session Manager requests that the PBX join Party A, Party B, and Party C to the conference call.
- The MVS Session Manager, through the PBX, ends the hold state from the SIP line call leg.
- Voice communication occurs among Party A, Party B, and Party C.
