Have you checked the /var/log/asterisk directory permissions?

I dont know how rsyslog is setup on your system but its possible it gets 
started as root, sees the destination file doesnt exist so creates it 
and sets the file permissions, and then drops down to running as the 
syslog user. At this point it doesnt have write permission to the 
/var/log/asterisk directory so cannot append to the file.
