Here’s a basic tutorial on how to use chan_btp:
This tutorial assumes you have a working copy of btpd and chan_btp is compiled into asterisk. If you don’t, grab the latest copy using the svn repository. See http://www.asterisk.org/download for more info.
1) Start the btp daemon by typing ‘btpd &’
2) Configure /etc/btpd.conf
report => gus:[email protected]:3856 ; where to send reports
discover => no
scan => 00:0E:6D:32:11:20 ; Your bluetooth device address goes here
If you have configured it correctly and your bluetooth device is detected, then you’ll see something like this in your console:
Already connected to '00:0E:6D:32:11:20'!
Disconnected from '00:0E:6D:32:11:20'

3) Configure /etc/asterisk/btp.conf accordingly
[locators]
locator => gus:test1,SIP/gus ; This should match your user:pass in your btpd.conf
[clients]
client => gus,00:0E:00:16:59:BF,SIP/5555555@yourprovider
In short:
The report line in /etc/btpd.conf ties in with the locators in /etc/asterisk/btp.conf
report => username:password@ip-address:port
ie. report using username and password to the machine at ip address and port
Since my btpd is actually running on the same machine, so I use 127.0.0.1. You can use multiple machines
running btpd that report to a central asterisk box.
4) Configure /etc/asterisk/btp.conf
The locator lines in /etc/asterisk/btp.conf list the usernames/passwords that will be sent
to it from the btpd daemon machines. So you should have one that matches.
locator => username:password,channel-to-use-when-detected
ie. listen for username and password and use channel-to-use-when-detected for calls
Then in the [clients] section you add the device and channel it should use when presence is not detected
client => name-to-use-in-dial-statement,device-id,default-channel-when-is-not-detected
5) Configure extensions.conf
exten => 200,1,Playback(pls-hold-while-try)
exten => 200,2,Dial(BTP/gus,60,m)
exten => 200,3,Hangup
Change it to whatever you want, you get the idea.
