[Asterisk-Users] Cannot compile chan_bluetooth on Asterisk 1.2.1

Ok, I did get this going (somewhat), and in case someone else has the
same issues I'll detail what I had to do.

First, I was using the instructions at
http://mundy.org/blog/index.php?p=79.  They stated that Asterisk at Home
2.2 already had all the rpms necessary for bluetooth and that I could
skip the yum install step.  I did, however, run the command anyways
after a few failed attempts.  There's an error in the rpm name, they
tell you to install bluez-libs, the correct name is bluez-libs-devel
(at least, that's what I needed to install).

I still couldn't compile the newest cvs version of chan_bluetooth, so
I again tried my trick of using the Makefile from an older version
(which used .tmp to compile) and it worked!  Once compiled, I
installed and started up asterisk.  I then received a message on my
phone asking if I wanted to allow asterisk to connect, and then asked
for a pin.  This took a bit of figuring out, but I got passed that. 
In /etc/bluetooth/hcid.conf, there's a line that says "pin_helper
/usr/bin/bluepin;" (it may have a different path, the important thing
is the pin_helper part).  Now backup the script in question, i.e. in
my case mv /usr/bin/bluepin /usr/bin/bluepin.bak.  Use your editor of
choice to create a new file with the same name, and in it enter:


#!/bin/sh -e
echo "PIN:1234"

Replace the 1234 with whatever you want your pin to be.  I don't know
if this is necessary, but I also edited /etc/bluetooth/pin to read:

1234

Again, 1234 should be whatever you want your pin to be.  I then
stopped asterisk, stopped the bluetooth service, started the bluetooth
service back up, started asterisk, then when my phone asked for a pin
I put in 1234, and it worked!

You may also need to make another edit to hcid.conf, under Local
Device Class change it to read class "0x200404;" or possibly "class
0x700408;".  This makes your bluetooth dongle look like a headset, and
not a data device (I experienced some flakiness until I changed this).

Now, I edited /etc/asterisk/bluetooth.conf appropriately (changed the
channel for the phone to 7, it's a Motorola V551), started it all up,
made some test calls and...no audio!  The cellphone works  great
otherwise.  It'll connect, stay connected as long as I want it to, and
when I hang up the asterisk extension the cellphone will disconnect
too.  Too bad I didn't realize 611 was a free call until after I made
a lot of test calls (it's a prepaid phone).  I did call our home
number directly to see if maybe I just had a one-way audio problem,
but nobody could hear a thing on either end.  I will continue to
troubleshoot this before I ask another question about it, but it's not
looking good.  BTW, the usb dongle I'm using is a Linksys USBBT100.
