Evolve IP Unified Communications vs. Kamailio SIP Server

I would leave it at the "?" rating because what can you rate them? 1 is too high. The only way they'd be "ok" is if: 1. Your company isn't growing and your users never leave the company. 2. You don't have to call support or make edits to the admin portal. 3. Don't need reporting. 4. Only use a physical phone to make/receive calls. 5. Do not plan to use a softphone or call center system. 6. Enjoy systems or people that frustrate you.

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.

• I'd like to see them build out API functionality for reporting off of call data within the organization. They have a Call Center product that seems to include a fairly robust reporting module, but it would be nice to be able to do some more of this within the standard Phone System product as well.

Support? If I could do everything myself with the time I don't have, I would do it better than their support. I don't like saying it that way, but it is the truth. We hired someone from another company that also used Evolve IP and when they found out that is what we used here, he expressed all of the same complaints and stories that we had.

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.
