​Computer Telephony

ExceleTel has been at the forefront of Computer Telephony Integration (CTI) for nearly 20 years. Our experience in the computer telephony development tools business with our flagship TeleTools SDK has exposed us to a very wide range of telephony applications, telephony platforms, and perhaps most importantly, the wide and sometimes very frustrating range of telephony issues that you too may experience.  From TAPI to VoIP to WebRTC and more, we have helped both developers and end-users all over the world navigate their telephony projects from concept to successful deployment.

​CTI, VoIP, TAPI, SIP, WebRTC, RTP, SDP, STUN, MOS, ...

... and the list of communications acronyms goes on and on.  At ExceleTel we can help you make sense of this alphabet soup in the context of what you are trying to accomplish. SIP is now the well established standard for VoIP. WebRTC is posed to be the next standard to transform the way we communicate.
