The development of Open-Source-solutions is getting more and more attractive and does not ignore the complex IT-landscapes any longer. We use Open-Source-software to fulfill your desires and to adapt the source code to your needs. The Open-Source-software used by us usually exists in a higher programming language and because there are given no restrictions in use, it can be individually adapted. Among the Open-Source-products, which we use and develop further, rank among other things Asterisk, PostgresSQL and Eclipse.

All functions of a PBX telephone system can be covered with the Open-Source-software Asterisk. Asterisk supports VoIP with different protocols and can be connected by means of favorable hardware with ISDN, PRI, POTS and PSTN.

Evision develops applications which supplement Asterisk in such a way that you can communicate more simply and more economically. Our Asterisk-applications are equally suitable for operators and private households. Asterisk supports language services such as answering sets, conference calls, language dialogues and listing services. The arrangement of a speech recognition is possible. Supported VoIP protocols are IAX, SIP, H.323, SCCP.

Evision developed a large measure of knowledge about Asterisk and collected beyond that also much application experience, so that we can develop almost all solutions around Asterisk that you like.
