Have you got extensions referenced in your dialplan that either don't have a 
corresponding entry in sip.conf, or where there isn't a device on the 
network?

I inherited a system with a similar problem.  The previously-installed 
Asterisk version  (some flavour of 1.2)  didn't seem to mind trying to dial 
non-existent devices; but the 1.6.2.9 that replaced it objected fatally.

I ended up making major  (i.e., stopping just shy of rewriting from scratch)  
edits to extensions.conf and sip.conf, pruning out sections that had lost 
their relevance, and everything was fine after that.
