[SIP foundry posted]Comparing Asterisk NOW, SwitchVox and Trixbox Pro with sipXecs
It is indeed difficult to provide a fair and in-depth comparison between Asterisk NOW, SwitchVox, Trixbox Pro and sipXecs, but we think that sipXecs has surpassed Asterisk based solutions both in terms of ease of use, features, scale, resiliency and quality by quite a large margin. The comparison below is not looking at what you could do using a Linux command line. It compares user accessible features through a Web UI or TUI. The comparison is based on freely downloadable and usable versions of the respective solutions, where Switchvox and Trixbox include closed source components.
