VoIP services convert your voice into a digital signal that travels over the Internet. If you are calling a regular phone number, the signal is converted to a regular telephone signal before it reaches the destination. VoIP can allow you to make a call directly from a computer, a special VoIP phone, or a traditional phone connected to a special adapter. SolTech can help leverage open source applications such as Asterisk to build highly competitive business driven applications with telephony at the core. Besides pure telephony applications, SolTech offers experience in the use of VoiceXML to help create voice driven applications on top of digital PBX platforms such as Asterisk or derivative works such as trixbox.
