Registration cascading is not possible (I think) but could it be solved 
with a shared dial route:

Instead of DIAL(IAX/sip.isp.com) could you not 
DIAL(IAX/sip1.isp.com&IAX/sip2.isp.com&IAX/sip3.isp.com) to reach a similar 
effect ? (or chain them in different lines so it tries to reach the first 
one, then the second one if it fails, and the third if that fails.
