VoIP is a demand or at least a request of many persons, however specially for large companies. People are afraid of going for VoIP just for cost optimization, leaving stability and reliability.
To convince people of the new products capable of handling reliablily VoIP, I suggest to publish a link of companies made a practical tests: to get idea of what I mean you can visit: http://www.tolly.com and choose document 200208
or download the following test: http://www.tolly.com/dynamic/Pdf_Temp/59456-200208.pdf
Of course VoIP tutorial and Voice & Data Convergence is a must on this site.
I’ll check the links out. Remember though: we’re not creating this site to promote Voice over IP. This site will be an informational resource. If there are downsides to VoIP, then we’ll be publishing them too!
