Bayonne is supposed to act as a key system, at least that's what was 
described on the web page. IMHO, it's probably a lot cheaper to re-use 
the old key system in tandem with Asterisk. A while ago, there was a 
discussion on this list about the feasilbility of re-using Toshiba key 
phone handsets with Asterisk. As it is, Toshiba has a Dialogic-style PCI 
card to support 16 digital handsets. Unfortunately, the cost of the card 
is >US$2500 - much more than buying a brand new key phone.

It would be pretty cool, if someone can reverse engineer the protocol(s) 
used by popular key phone systems. I think it's possible to use HFC in 
NT mode to drive those handsets. IIRC, most digital phones work along 
the lines of ISDN phones.

Cheers.
