Let us first know what is the VoIP SIP SDK is all about, the SDK stands for Software Developer Kit which means that this is the kit that contains all the tools and methods that you may need to set up a dial and receive soft phone to your application. It is a powerful kit that contains all the features that will turn your soft phone to be like a real one, except that you are paying much less money.
The first added feature, which was added in the 1.1 VER, is to play an audio file while the conversation is taking place. This means that you can let your client listen to an audio file before you continue talking to him. Not only that but you will also get an alert when the playing is finished so, there won't be a pause but you will pick up the conversation after the audio playing is finished. The supported file type is WAV which is the best for internet usage because of its small size.
