32 + * Asterisk -- A telephony toolkit for Linux.

41 + *
42 + * This program is free software, distributed under the terms of
43 + * the GNU General Public License
44 + *
45 + * ******************* NOTE NOTE NOTE NOTE NOTE *********************
46 + *
47 + * This code is not at all tested, and only been developed with a
48 + * HBH-200 headset and a Nokia 6310i right now.
49 + *
50 + * Expect it to crash, dial random numbers, and steal all your money.
51 + *
52 + * PLEASE try any headsets and phones, and let me know the results,
53 + * working or not, along with all debug output!
54 + *
55 + * ------------------------------------------------------------------
56 + *
57 + * Asterisk Bluetooth Support
58 + *
59 + * Well, here we go - Attempt to provide Handsfree profile support in
60 + * both AG and HF modes, AG (AudioGateway) mode support for using
61 + * headsets, and HF (Handsfree) mode for utilising mobile/cell phones
62 + *
63 + * It would be nice to also provide Headset support at some time in
64 + * the future, however, a working Handsfree profile is nice for now,
65 + * and as far as I can see, almost all new HS devices also support HF
66 + *
67 + * ------------------------------------------------------------------
68 + * INSTRUCTIONS
69 + *
70 + * You need to have bluez's bluetooth stack, along with user space
71 + * tools (>=v2.10), and running hcid and sdsp.
72 + *
73 + * See bluetooth.conf for configuration details.
74 + *
75 + * - Ensure bluetooth subsystem is up and running. 'hciconfig'
76 + * should show interface as UP.
77 + *
78 + * - If you're trying to use a headset/HS, start up asterisk, and try
79 + * to pair it as you normally would.
80 + *
81 + * - If you're trying to use a Phone/AG, just make sure bluetooth is
82 + * enabled on your phone, and start up asterisk.
83 + *
84 + * - 'bluetooth show peers' will show all bluetooth devices states.
85 + *
86 + * - Send a call out by using Dial(BLT/DevName/0123456). Call a HS
87 + * with Dial(BLT/DevName)
88 + *
89 + * ------------------------------------------------------------------
90 + * BUGS
91 + *
92 + * - What should happen when an AG is paired with asterisk and
93 + * someone uses the AG dalling a number manually? My test phone
94 + * seems to try to open an SCO link. Perhaps an extension to
95 + * route the call to, or maybe drop the RFCOM link all together?
96 + *
97 + * ------------------------------------------------------------------
98 + * COMPATIBILITY
99 + *
100 + * PLEASE email <theo@adaptive-it.co.uk> with the results of ANY
101 + * device not listed in here (working or not), or if the device is
102 + * listed and it doesn't work! Please also email full debug output
103 + * for any device not working correctly or generating errors in log.
104 + *
105 + * HandsFree Profile:
106 + *
107 + * HS (HeadSet):
108 + * - Ericsson HBH-200
109 + *
110 + * AG (AudioGateway):
111 + * - Nokia 6310i
