I have been begging for a professional version of Switchvox for years. By that, I mean a version where more is left to the admin to configure, especially when it comes to SIP trunking. I mean a version that lets you use multiple NICs on the device to avoid NATing, ALGs, and other nasty scenarios. And a version with access to the Asterisk CLI so you can troubleshoot, debug, etc. All while maintaining commercial support, and general ease of use for day-to-day administrative activities that Switchvox is known for.
