I haven't tried MISDN yet, the installation looks much more complicated 
than bristuff but to answer your first problem...

Are you sure that your telco is passing calls on all 3 MSN's? Bristuff 
doesn't decide which MSN rings on which B channel.  It just detects and 
handles accordingly.

If you never see a call coming in on the console for that MSN I would 
check with your telco first. Increase the verbosity of asterisk to find 
our what is going on.
