Hi Hans,

As mentioned in my previous post - I've had this working for a number of 
years for my personal use. When I would go abroad, I would leave my 
cellphone/mobile phone home connected to Asterisk over bluetooth. I 
would say that if you're having problems staying connected - it might be 
the bluetooth dongle. It seems that the ones with the Cambridge Silicon 
chipset work best. In my case, once the phone gets connected, it stays 
connected. However, there is a known bug whereby Nokia phones 
automatically disconnect from bluetooth at the end of a call. To bypass 
this, I reduced the number of seconds to 5 in chan_mobile.conf - so that 
Asterisk tries to scan for the phone quick enough after it disconnects. 
I've added a note at the bottom of this page a while ago regarding this 


At the time I also got hold of as many phones as possible and tested 
compatibility. I've added my results to the same page above.
