voip-info.org has been a really useful resource during our various VoIP implementations. I oversee VoIP operations at Xand Corporation where we run Asterisk with Cisco 7960 and 7912 telephones. At home I run Asterisk with Grandstream GXP-2000 telephones (mainly because the GXP's are the only decent IP phones with backlit displays — which double as night lights in my kitchen and bedroom!). I'm also in the process of adding Asterisk integration to the Citadel email/collaboration/groupware system, enabling the whole "universal inbox" thing. I can be reached at UNCENSORED! BBS.
