Facts after some humble detective work done last night (using trunk
revision 96988):

1. These idle console disconnects for me were related to registry =>lines
on my sip.conf as stated above so I checked it again and it seems to be
something wrong when sip_reg_timeout is called but only when you type
something on CLI.

2. While chan_sip keeps trying registration everything looks fine. Even
with softphones logging in automatically at the same time. You just can't
touch the CLI :-)

3. You can execute CLI commands as much as you like, until the first DNS
error/registration attempt gets a timeout.

4. Whatever I set global_regattempts_max or not, the problems still
occurs.

5. The problem simply vanish if I hack the if (r->call) statement on line
8328 with a bypass. The most isolated code within it seems to be the guilty
r->call = dialog_unref(r->call); on line 8343 causing the CLI freezes on
registrations for both local and remote connections. Yay!

6. This dialog_unref returns NULL and tweaking it solves the problem
partially, sigh...

7. I also got 'Bus error' and crashes on some rasterisk executions while
playing with tab completion, but I believe they might be a undiscovered
bug, so I'll double check it before correlating it with this bug.
