Yes they're ADSI.  They work very well with *, to the extent that * has ADSI 
support.  (meaning * does not have complete ADSI support, but whatever * 
DOES support, these phones use just fine.)

The Bell Vista 350/450 phones are just rebranded Aastra phones.  The wiki 
has information on how to unlock all these phones so you can load up your 
own ADSI programs, even in slot #2 (the autostarting slot).
