Hi,
The Asterisk-Dev list is talking about bt... ounce again...
Since I'm (really) not an expert in this kind of stuff, I would like to
have your opinion.
Here is a copy of my last reply to this list.
Note: I'm not in the bluez-devel list. Too much mail... :-(
Please don't forget to add my email address to your reply.
Thanks a lot, J?r?me.

First... I guess we should all focus on SCO support for bluez:
http://www.bluez.org/todo.html
Then... this is another step :
* -> headset
* -> cellphone
2 kind of chan_
Then... SMS (easy), least cost routing (obvious), directory synchro, and
other features.
Why don't you send the bounties to bluez???

(I may be wrong... but that's the way I see the bt integration stuff).

Hi Marcel
Thanks for your answer. I have more questions - Tell me if I'm off topic
for the list.
> what you first need is correct ALSA-SCO-Bluetooth integration.
Yes, I understand this... my idea is (was?) to collaborate with an
existing projects, at least to get advises and have a "good" framework.
I'm trying to have an idea of the "State of the Art"... existing
projects, what works, what doesn't works, common issues...
Since a few weeks, I have the following links in my bookmarks :
(a) Bluetooth headset driver for ALSA - snd-bt-sco
http://www.dcs.gla.ac.uk/~jp/snd-bt-sco/
According to the original site, its current status is: "this driver
is not the proper way to implement headset capabilities, and somebody
else will hopefully come up with a better solution".
(b) http://www.gargan.org/linux/snd-bt-sco/
They have patch a kernel patch for snd-bt-sco(a). And a new btsco-0.3...
Maybe (I hope) they have the "proper" way...
(c) Handsfree and Headset support for BlueZ -
http://www.soft.uni-linz.ac.at/_wiki/tiki-index.php?page=ProjectBluezHandsfree
I haven't tested it for the moment.
(d) kbthandsfree - http://kde-bluetooth.sourceforge.net/
It seems very advanced... but maybe to too much integrated to qt/kde, I
will have to spend hours to "understand" the code :-) We need something
small for telephony applications.
-> Are you aware of other free projects implementing sco features?
There is also on your web site - http://http://www.bluez.org/todo.html
the "todo" page :
"sco audio stuff
* Full support for SCO connections with the HCI USB driver
* Simple API for adapters with PCM interface
* Native integration with ALSA for Linux 2.6"
-> Is it the "correct" ALSA-SCO-Bluetooth you're talking about?
I'm also going to get in touch with projects (a)(b)(c)(d) to get more
info... maybe some of their dev are also in bluez list?
Then, if you are interested, I could send some kind of little
"synthesis"... for you web site.

Restrictions,
-> Because of the mobile phones (harware/firware) ?
-> Or because of BT - SCO (in theorie) ?
Best regards, thanks again.
J?r?me.

Just wanted to drop a note that we still try to improve things on this:
http://sourceforge.net/projects/bluetooth-alsa/
We are still stuck with the not-that-good structures of snd-bt-sco, but
I think this will improve eventually. If anyone wants to develop
something in this direction, it would be great if you could team up with
us :)

Just a bit of advice. If anyone does any contributions to Asterisk, for
those contributions to be accepted, one has to sign over one's copyright
to a single Asterisk developer.
So, if one wishes to keep copyright over one's work, do not contribute
to Asterisk.

as long as there are no mobile phones with cordless telephony (CTP)
support I think it makes no sense to think about the integration into a
PBX. You will be hit by the restrictions of the headset/handsfree
profiles, because they are designed for a different approach. However,
what you first need is correct ALSA-SCO-Bluetooth integration.
