<p>In the thesis the advantages with Text over IP (ToIP) is explained and it is motivated why it is a good idea to integrate this in Asterisk. It also presents an implementation of a ToIP extension in Asterisk.</p><p>ToIP means communicating over a network based on Internet protocols with real-time text. Real-time text means a character is sent to the receiving terminal as soon the sender has typed it or with a small delay.</p><p>In the thesis IM and ToIP is compared in a survey. The result point at IM is not better than ToIP even though it is much more commonly used. VoIP can not replace ToIP either because there are occasions when ToIP is better for instance if the person using it is deaf or if a person want to make a private conversation in a noisy room.</p><p>Asterisk is an IP-PBX. PBX stands for Private Branch Exchange which means a private telephone system which is part of a larger network system that exchange information.</p><p>An IP-PBX is a PBX based on the Internet. Asterisk and many other IP-PBX can also exchange calls between the PSTN ant the Internet. By including ToIP in Asterisk it will be possible to exchange ToIP calls.</p><p>The implementation described is not only including ToIP in Asterisk but also a translation function between the text format called t140 and another text format called t140 with redundancy.</p><p>The idea is to extend the translation function in the future to more text formats.</p>
