I have been tasked to prepare a plan to upgrade our analogue telephone system into a full-IP unified communications system. We have an experimental Asterisk VOIP system running and its working fine as a workgoup VOIP solution.
However, we don't have data on it for systems having a large number of users (500+). This is critical as we plan to replace all our analogue lines with a new VOIP system. For those of you who have experience using this as your IP communications system, I would like to know your experiences with using this product. Any comment or suggestion would be highly appreciated.
