Brian, all,

For any others that might be attempting such a migration, I think I have 
the setup OK.

It seems to be sufficient to enable multiple registrations on FS, then 
at least on SNOM leave everything at default (no SLA!) other than 
disabling call waiting, and assign a "line" button for your "multicall" 
number. This appears to work as I described, incoming calls to the 
number ring on all registered phones, flash the button and pressing it 
picks up. If all the phones are busy the call goes to VM. Voila!

Cheers

Alex
