sipXecs product is built with a variety of different computer languages, from C, to Python, to Java to Ruby. sipXecs also leverages other open source projects from FreeSWITCH to OpenACD to OpenFire. And it goes without saying that sipXecs uses a variety of different libraries from PCRE for C++ code to Spring Framework for Java Code. Don't be overwhelmed, no one knows every computer language, application or library, so ask for help on sipx-dev@list.sipfoundry.org.
