+ * Asterisk -- A telephony toolkit for Linux.
+ *
+ * Asterisk Bluetooth Channel

+ *
+ * This program is free software, distributed under the terms of
+ * the GNU General Public License
+ *
+ * ******************* NOTE NOTE NOTE NOTE NOTE *********************
+ *
+ * This code is not at all tested, and only been developed with a
+ * HBH-200 headset and a Nokia 6310i right now.
+ *
+ * Expect it to crash, dial random numbers, and steal all your money.
+ *
+ * PLEASE try any headsets and phones, and let me know the results,
+ * working or not, along with all debug output!
+ *
+ * ------------------------------------------------------------------
+ *
+ * Asterisk Bluetooth Support
+ *
+ * Well, here we go - Attempt to provide Handsfree profile support in
+ * both AG and HF modes, AG (AudioGateway) mode support for using
+ * headsets, and HF (Handsfree) mode for utilising mobile/cell phones
+ *
+ * It would be nice to also provide Headset support at some time in
+ * the future, however, a working Handsfree profile is nice for now,
+ * and as far as I can see, almost all new HS devices also support HF
+ *
+ * ------------------------------------------------------------------
+ * INSTRUCTIONS
+ *
+ * You need to have bluez's bluetooth stack, along with user space
+ * tools (>=v2.10), and running hcid and sdsp.
+ *
+ * See bluetooth.conf for configuration details.
+ *
+ * - Ensure bluetooth subsystem is up and running. 'hciconfig'
+ * should show interface as UP.
+ *
+ * - If you're trying to use a headset/HS, start up asterisk, and try
+ * to pair it as you normally would.
+ *
+ * - If you're trying to use a Phone/AG, just make sure bluetooth is
+ * enabled on your phone, and start up asterisk.
+ *
+ * - 'bluetooth show peers' will show all bluetooth devices states.
+ *
+ * - Send a call out by using Dial(BLT/DevName/0123456). Call a HS
+ * with Dial(BLT/DevName)
+ *
+ * ------------------------------------------------------------------
+ * BUGS
+ *
+ * - What should happen when an AG is paired with asterisk and
+ * someone uses the AG dalling a number manually? My test phone
+ * seems to try to open an SCO link. Perhaps an extension to
+ * route the call to, or maybe drop the RFCOM link all together?
+ *
+ * ------------------------------------------------------------------
+ * COMPATIBILITY
+ *
+ * PLEASE email <theo@adaptive-it.co.uk> with the results of ANY
+ * device not listed in here (working or not), or if the device is
+ * listed and it doesn't work! Please also email full debug output
+ * for any device not working correctly or generating errors in log.
+ *
+ * HandsFree Profile:
+ *
+ * HS (HeadSet):
+ * - Ericsson HBH-200
+ *
+ * AG (AudioGateway):
+ * - Nokia 6310i
+ *
+ * ------------------------------------------------------------------
