Thanks for the config info. I have a couple of suggestions for fixes.

1. Try changing the type in [basic-options] from friend to peer. I've found that 
device state reporting for outbound calls (from the perspective of the phone) 
tends to be more accurate with this type.

2. If for some odd reason number 1 either doesn't sound appealing to you or 
doesn't work, then try moving the limitonpeers=yes option from your 
[basic-options] section to the [general] section.

No, neither of these ideas actually make any real sense to me, but they are 
based on behavior that I have witnessed with my Asterisk setup in my office.
