[Bug 442424] [NEW] cellphone recognizes paired Ubuntu computer as headset

[Martin Emrich]

Public bug reported:

Binary package hint: bluez

Since a few weeks, whenever someone calls me on my cellphone while I am
in range of my laptop (running current karmic amd64), I do not hear the
person, and I see the headset symbol on the phone (HTC diamond with
Windows Mobile 6).

The phone is paired with my laptop, as I sometimes use it via bluetooth
PAN to use mobile broadband.

At first, I though my headset accidentally turned on while lying around
in my room... :) But that wasn't the case. It was my laptop that got in
between. I saw this in my syslog just now:

....somewhere here I "panicked" and hit the wireless killswitch to save
the call, but it was too late...

Ubuntu should either display some visual feedback that it grabbed the
call from the phone and offer an option to disable it, or should not do
it in the first place.
