Abstract [en]

In this thesis we will discuss how to implement a ToIP device that enables communication with a standard textphone over Internet Protocol using open software and hardware solutions. We will make an analog to telephone adapter capable of supporting Baudot textphones with the help of the software Asterisk, Open Baudot and the hardware platform IP04. We will discuss if the use of this device, if it is outdated already. We have performed practical testing of our solution and compared it with a voice channel setup.
