Kamailio SIP Server is very well suited if you want to secure your main servers; it can perfectly act as a proxy server and a gateway to your main server. It also does load balancing and call transfers easily based on the configurations done.

If you get less than 4 phones you fall into the online only customer service. There were a couple of times that I could have used more assistance but figuring it out online was a bit of a hassle.

8x8 has a much lower cost that avaya for the same features. 8x8 is a bit more user friendly than some other larger well established brands. It still uses industry standards in terminology and call flows to for anyone with voip experience its a pain free switch to make over.

As Kamailio SIP Server is an open source, the major impact is on cost; it's free to use compared to any other Softswitch or server in the market. You can also customize it to your need and use the features that you need, which is one of the major plus points for the Kamailio SIP Server. And one server is enough to handle thousands of calls simultaneously.
