CallWeaver (formerly OpenPBX.org[1]) is a fork of the Asterisk PBX software. CallWeaver was forked from Asterisk 1.2 in September of 2005. The fork took place because a number of developers found that their needs and vision for the project differed from those of Digium the leaders of the Asterisk PBX project.
Principal Differences from Asterisk
editThe most important differences between Callweaver and Asterisk are built-in STUN support, the use of SpanDSP for better codecs and full T.38 fax over IP support, Sqlite instead of Berkeley DB, a universal jitterbuffer, the use of POSIX timers to avoid Zaptel timing dependencies.
Licensing
editCallWeaver is licensed under the GPL only, contributors do not need to assign or disclaim their contributions to the CallWeaver project. This also means that CallWeaver is not able to take advantage of some of the GPL exemptions that digium granted to itself with Asterisk.
Status
editCallweaver is presently working towards a first stable release.[2]
