Yet Another Telephony Engine (YATE)
YATE has a very minimalistic architecture and exposes most of its features through an external protocol. Since this external protocol is a simple text protocol, it can be written quickly in any language. There are libraries for Perl, PHP, and Python. At the moment, YAYPM is the most advanced YATE connector library.
YAYPM uses the Twisted framework and Python generators to allow programmers to write prototypes rapidly. Since Twisted is a huge protocol library, it is easy to mix telephony applications with protocols such as HTTP, SMTP, and SQL.
