[Asterisk-Users] GSM phones, bluetooth and general happiness

[Jay Milk]

Even better... Come home, leave the phone in the car knowing your
bluetooth gateway is only a few feet away dangling down from the garage
ceiling :)  I already have bluetooth handsfree in the car, and it's
sweet -- no more missed calls due leaving the phone on vibrate.

Interesting.... 

We use primicell's (nokia 22's) to break out mobile phone traffic at the
office. I know these are more like full blown mobile phones that u plug
directly into the pbx but similar idea. Would be cool to have a home
version to allow u to get similar functionality by just putting your
bluetooth mobile near your asterisk server ;-) 

ie. Come home, plonk phone down. walk off to another room - girlfriend
calls, asterisk picks it up and rings all phones in house... no annoying
ear bashing about why I didnt take my mobile with me and when I call her
I can do so on my dirt cheap mobile-mobile rate :-) 

On a similar note - has anyone got asterisk to work with the nokia/sony
PCMCIA GSM (or even 3G?) cards? - 3G would open up the Videophone thing
through asterisk - sure there is a very good technical reason why that
wouldnt work!!!
