tyntec provides a wide range of audio formats with which the audio data can be transported. The format used is negotiated between the parties at call setup. If you want a specific audio format that is not offered by the tyntec platform, please talk to tyntec’s technical support so that we can assess adding the additional audio format.

Furthermore, there are regional and technical limitations, so please note that not every codec is available for every country or network.

A recommended and commonly-used audio format is G.711. Upon request, tyntec offers other formats as well, such as G.726, G.729ab, G.723 or iLBC.
