I don't use SIP for one, and I forward udp/4562 to my * box from the 
firewall...  of course now what happens if you have to upgrade the 
firewall?  :-) 

I think the basic solution is a cluster.  That way you can upgrade in pieces 
without losing functionality.  There are T1 monitoring/switching devices 
which will let two boxes share a single T1 and "fail over" immediately, 
although you'll lose the calls in progress.
