Bluetooth headset and Wireless router

Hi,
I am currently trying to develop a way to connect a wireless bluetooth
headset to my bluetooth linksys router. I then want to connect to
freeworlddialup.com . Does anyone have any ideas on how this could be
accomplished?

Thanks,
Tom

see if you find something interesting here:

It can't. The headset needs to talk with something that handles the calls.
That device would need bluetooth, of course. The choices are a PC program,
cell phone and even some cordless phones (uniden's 5.4gHz). But the router
itself has no means of picking up the Bluetooth signals. Even if it did
there's no software (or room for it) on the device.

So without some intermediary program it's not going to work.

In principle one can hack many of linksys routers (www.openwrt.org) and
use just about any linux software on it. Anyone to give it a try ?

And connect the BT portion of it, how? There's no BT radio in the unit.
Sorta key to making a headset work, isn't it? Not to mention the CPU in the
linksys has nowhere near the processing power necessary to handle signal
encoding and compression.

So try all you want but without a way to actually pickup the signals and
encode them it's a fool's errand.

But some units have an USB port where an external Bluetooth dongle can
be plugged in. See http://forum.openwrt.org/viewtopic.php?id=3D1650 for
example.

Bluetooth audio is uncompressed 8 bit 8kHz PCM data, so there's no need
for processing power on the Bluetooth side (hey, the average mobile
phone's CPU is even weaker!). As for the VoIP side ... I don't know
about the specific provider that was mentioned, but in general it is
possible to negotiate the the codec to use when setting up the
connection. Uncompressed audio should be available as a possible codec.

So, in principle it should be possible to use one of the OpenWRT
thingies to directly connect a Bluetooth headset to a VoIP provider.
(However, I'm not aware of anyone who did this yet.)

Nobody seems to have asked the obvious question. What model of Bluetooth
Linksys router do you have? I can't find any bluetooth routers on the
Linksys site.
