You need a Bluetooth device which supports the
headset profile and either an internal Apple Bluetooth module or a D-Link DBT-120 USB adapter:

Have a look for a device which supports the headset, handsfree and A2DP profiles. Then you are most compatible and ready for the future but your Anycom BSH-100 (right?) should have headset support on board.
Using a headset needs several steps even needed if you have the latest computer or Mac OS X release. Please make sure to follow them in order.
- Download the Apple Bluetooth Firmware Updater
- Install it
- Launch it from Applications > Utilities > Bluetooth Updater
- Apply it to your adapter (takes very long).
- Start the Apple Bluetooth Assistant and select Headset. Do not use anything else!
- Make your headset Bluetooth visible. For your Anycom hold the Vol Up & ON/OFF button for 4 seconds.
- Now select the headset in System Preferences > Sound.
In most cases step 3 is missed. You have to start the installed updater yourself (do not ask me why). Step 4 fails if your Bluetooth USB adapter is not supported by Apple and you have to go for a D-Link DBT-120 USB adapter.
Normally you call it profile, service or how you like it. Technically it is a protocol stack: several protocols layered on top of each other creating this service.
