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

++ * Copyright (C) 2004 Adaptive Linux Solutions
++ *
++ * 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
++ *
++ * ------------------------------------------------------------------
++ *
++ * Questions, bugs, or (preferably) patches to:
