Speakeasy VoIP - secure?

["Phil Cryer" <phil () cryer us>]

I'm considering going with Speakeasy for their VoIP, but I'm trying to determine how 'secure' their secure marketing 
statement really is.  I like that the the phone box won't be POTS, but a box to branch off of my exising DSL modem, but 
these are still outside of my firewall.  Anyone with experience or opinions on this setup, please tell.

Regards
