No, because Asterisk have no module that let it "share" important information 
about stablished calls.
Also if Asterisk is mananing any kind of TDM card not running in SS7 mode, 
it's also impossible.

It's supposed that on Asterisk 1.6 changes have been introduced to support 
some kind of clustering but I don't know how it will work
