Multipoint Configuration
We’ve described in previous articles how the MDA 200 can allow you to switch your USB headset connection between a PC softphone and a desk phone. In this configuration, the Plantronics Voyager Bluetooth headset combined with the BT300 Bluetooth stub allows the headset to be linked to both the desk phone and the PC, while the multipoint capabilities of the Voyager headset allow it to also pair with your mobile phone. The HL10 handset lifter connected from the MDA to the phone allows desk phone calls to be initiated and ended remotely without the need to manually pick up the handset.
Active Phone Call
The basic principle is illustrated to the left. A call may be initiated by selecting the Call Control (CC) button on the headset. This signals the MDA to lift the phone handset thus initiating or answering a call. Calls can also be managed by selecting the PC or Phone buttons on the MDA. Selecting the phone button will cause the handset to lift as well as Linking the Bluetooth stub to the headset.
Here are some operational tips we noticed in testing this configuration:
MDA connected only to the Desk Phone (not the PC)
- Both the PC and Phone LEDs will be off initially. Selecting the CC on the headset will activate the Link and pick up the phone handset
- If the phone rings, the user is alerted by beeps in the headset, and the MDA phone LED will flash. You can answer the call using the CC button or by selecting the MDA phone switch.
- During an active call, selecting the headset CC button or the MDA phone button will end the call and hang up the phone handset.
MDA connected to both Desk Phone and PC
- Initially the PC LED will be illuminated
- Selecting the CC button on the headset will NOT activate the phone. It is signaling the PC softphone at this stage. This has relevance depending on the Softphone you are using, and whether you have the Plantronics control software loaded on your computer. (This topic is discussed in the MDA 200 user manual.
- If the phone rings, the user is alerted and may engage the call using either the CC button or the MDA phone button.
- The MDA reverts to PC mode when the desk phone call is ended.
The following table provides the LED indicators for various operational modes.
