[Asterisk-Users] chan_bluetooth and Ericcson T68 problem

[Vlasis Hatzistavrou - asterisk mailing list account]

Hello Enky,

We have encountered similar problems with various Ericsson & Nokia 
phones. We couldn't get the channel driver to work 100%. However, we 
cannot actually tell whether it was our mistake or whether there was a 
problem with the channel driver. We tried to contact the driver's 
maintainer/creator but no luck...

If you manage to find a solution for this problem we'd also be 
interested to know about it.

Best regards,
Vlasis.
