Toshiba Phone System

How can I learn about IP telephony ?

Is there a CBT or a training course for IP Telephony or VoIP that you can guide me to? (I already know Cisco Web Site) :-)

2. I'd recommend against the CTP exam, I haven't found _any_ meaningful documentation there. There seems to be a pretty good community growing up around Asterisk, and obviously freeware is a good place to get your hands in for minimal $$. You could do worse than "Asterisk: The Future of Telephony" published by O'Reilly. I also really liked Cisco's CIPT course, although that's not cheap, you do get your hands on Enterprise-class hardware. You could also sign up for a mostly-free IPT service like The Gizmo Project, which you can even get working with SIP phones (my favorite is the Cisco/Linksys SPA-941)
