Free PTLib compiler for Windows
Screenshots
OpalVOIP Is a free PTLIb compiler for apps that use VOIP functions, such as Nimbuzz and Messenger. It uses Visual Studio for most of the work, but you can also use optional programs like OpenSSL.
The program automatically detects which one you are using and will compile the system for you. It also checks for incorrect configuration paths, informing you so that you can fix them. The download and installation options are limited, so you’ll need to check the process for your specific Windows operating system.
Installation packages
When OpalVOIP builds the PTLib library, it searches for which package is available. Each installation package serves a different function. For instance, OpenSSL is used for authentication and call encryption. FFMPEG contains support for video and audio files. You can also use libjpeg for static JPG files and videos or Lua for scripting.
Coding standards
Coding is done using C++ standards, but there may be a few variances. OpalVOIP has a complete WiKi library devoted to the correct coding methods for any of the packages. You can also remove compiler warnings at the same time to avoid confusion.
Making calls via commands
To activate calls, OpalVOIP uses commands via a gateway between H.323 and SIP telephone networks. Some of these charge for calls made while others are free. However, not all of them are compatible with the compiler, so you’ll need to test several of them.
Mailing lists
OpalVOIP also offers mailing lists using specific C++ commands if users want to make postings. These are used for any queries related to the VOIP technology. However, there’s a cutoff for when the traffic becomes too high or someone abuses the system. You can also create a searchable archive of all past mail if you’re looking for content you’ve missed.
Calling via the internet
Many messaging apps are moving towards VOIP to make video and voice calls more secure. Developers use programs like OpalVOIP to code these applications, granting new features to your chat space. However, you need vast coding experience to understand how it works and to write programs according to the right standards.
