Though Mexuar has published the source code under GPL the download only contains the plain Java sources. There is no documentation except for JavaDoc, no build script and no sample code. The link to the download is quite hidden on their website. While Mexuar offers paid support, licenses and manged hosting there doesn’t seem to be an Open Source community around it yet. Tim suggested to set up a project on Sourceforge or Google Code to build one. However due to his former relationship with Mexuar he prefers not be the project lead.
I think the code is a great complement to Asterisk-Java and will be very useful for a lot of applications. If you are also interested in giving it a good home and add some polish feel free to comment on this posting or discuss it on our mailing list.
