It is important to notify users about new releases of the software, so they may download and install the latest available version with new features and/or bug fixes.
Every time the softphone starts, it connects to the server and check, if new version is available.
This connection to the server is done via HTTP protocol (see below diagram).
A web server should return a web-page in specific format.
The request should contain 3 fields separated by ‘|':
- First field is a version number of the latest release available for downloading.
- Second field is URL of web-site, which user should visit for downloading the latest release.
- Third field optional. It is a text, which will be displayed to the user, if his program version is less then stated in the first field.
The softphone will parse the result from the server and compare received version number with own version.
If the server contains newer version, the softphone will notify a user about new version is available on the server.
URL of check for update web-page is configured in installer-brand.nsi file
