I have the same headset and experienced the same problem.

This error message prevents the initial handshake with the headset from 
completing.  I have implemented a response for this message, and the next 
message that is sent, and can now get calls working on the headset.

It's not bug free but at least you get calls through.  Here's my hacked 
version.  I also started fixing some problems in the init/shutdown code too.
