Synth is a C++ template framework - a set of components that can be mixed and matched to build the right functionality; furthermore, components are loosely-coupled, designed to be both extensible and replaceable. Synth blurs the line between compile-time and runtime, and it does so by blending the static C++ type system, the dynamic values that need to be manipulated and formatted, including those from other languages, and the templates to do so. The name is an allusion to this synthesis process, which combines values to generate new ones (streams, files, strings, numbers, etc.)

WikiPBX is a PBX Web interface for FreeSWITCH. Multiple "accounts" are supported per server instance: each account is effectively a completely independent PBX. Configuration is layered so that XML files go on top of what is stored in the database. This allows you to use a database, but stays out of your way if you choose to use flat files. Extensions, SIP endpoints, and gateways can be configured via a Web interface. Live calls can be viewed, hanged up, and transferred. Call history (CDR records) can be viewed over the Web interface. There is a Web interface for managing IVRs. "Sound clips" can be easily recorded for use in dialplan or IVRs. Audio or text-to-speech can be injected into live calls.
