Source Code & GPL Open Source
Source Code
The source codes of the components used by snom in its VoIP phones and covered by the GPL can be found in the following table for download.
The exact wording of the GPL can be downloaded here. The source code can be downloaded in compressed form. 'tgz' stands for .tar.gz, which means that it is a TAR (Tape ARchive) file compressed with gzip (GNU zip).
TAR allows many files to be combined into one large file while retaining their folder structure and is used, among other things, to move large collections of files into a single file, such as for some downloads at snom.
To decompress and access the files, you need a programme like tar and gzip for your specific computer platform.
