Make your App More Social

Rebtel’s Voice Platform and its powerful Software Development Kit makes adding voice to your Android or iOS app as easy as can be. The SDK has been designed from the ground up to facilitate simple and quick integration by cleverly wrapping all the signaling and codec handling into one. This lets you focus on your app’s user experience rather than the nitty gritty technical details, while seeing gaining frequency of use and higher perceived value as a result.

Fast and Simple Integration

With integration that can be completed in 15 minutes, Rebtel’s SDK offers unparalleled ease of use. Instantly after dropping the library in Xcode or Eclipse, you can get started with setting up the logic and call-handling methods you want to have in your app.

HD Voice Quality

The SDK relies on the same thoroughly tested back-end used daily by millions of Rebtel’s own users, effectively ensuring the highest reliability and up-time. Your users will experience full duplex voice with crystal clear quality over iSAC (internet Speech Audio Codec) even if the data connections are poor.

Free of Cost for any Developer

The best things in life are free. Integrate voice in your app for no cost regardless if your user base is in the hundreds or millions. You don’t even have to make a costly initial investment in back-end or infrastructure. We take care of that, while you can focus on building a great app.


Rebtel’s SDK allows us to bring a simple, yet powerful and thoroughly road-tested calling functionality into our app.
