Some phones with HFP Audio Gateway version previous to 1.5 (e.g.
Samsung SGH-D600 returning 0x0101 as profile version) do not accept an
AT+BRSF with latest features. The Handsfree agent should adapt its
AT+BRSF command depending on the remote version, so add version
information as parameter of NewConnection method.
Here is traces of buggy exchange:
