[Asterisk-Users] Cannot compile chan_bluetooth on Asterisk 1.2.1

Wed Jan 25 23:28:43 MST 2006

Again, my documentation is still sparse.  I should have noted that the
phone will recognize asterisk and connect even if the channel in
bluetooth.conf is configured wrong.  You'll just get no audio, or
disconnects, or what-not until it's set correctly.  So realize that
later on when you're testing.  Also the usb dongle must have a CSR
chipset, else it won't work (well, at least probably won't work, I'll
provide instructions on how to tell if it should work or not later).

Here's the relevant instructions on
http://www.crazygreek.co.uk/content/chan_bluetooth for how to dial
out:  Send a call out by using Dial(BLT/DevName/0123456).

As far as dialing in, there's a special context (I think [bluetooth]
maybe?  I'll have to get back to you on that).  I know that it should
work fine, because I tried dialing the phone, asterisk picked it up
then immediately disconnected because there was no context for it to
go to (I think it tried to fall back on [default], which I didn't have
configured to accept an incoming call).

Good luck!
