About Kasteris
Hi, my name is Marc Orenberg, and Kasteris is my software consulting company.
I have over 12 years experience in the software industry, much of it in the
telephony and network programming fields, but I am also experienced in writing
websites and graphical user applications.
While I specialize in telephony applications, I am part of a small
network of professionals with many different specializations. So I am able
to handle projects of all types and sizes.
Open Source Telephony Projects
Asterisk and FreeSwitch are powerful and flexible open source frameworks for creating telephony
applications. They may be used to create PBX's, call center applications, IVRs,
conferencing applications, and much more.
For telephony projects, I have a fully functional test lab available, where
my customers can dial-in at any time to test and/or demo their application.
I can also provide hosting and phone service for customers.
