Not without some very extensive programming. VOIP (Voice over Internet Protocol) sends data via TCP/IP packets.
All data coming over the internet is going to be a TCP/IP packet so your program will have to deal with a lot of data. Their are many other factors that you would need to take into consideration which would take awhile to explain.
I can tell you from my experence as a Net+ Certified and currently a network technician is its not going to be easy.
Some things you will need to know/understand:
- ISO Model (Network model which is a must and some what complicated)
- Understand how void packets work
- Understand how packets work and are structured
- Understand how to process a packet
- Filtering
Their are a couple more things but the main point is you really need to know how packets work, and how voip works with it. If you understand both of these its more about the coding which I am a C++ person so I cant tell you much about C related issues (even know they are somewhat related). Either way from a programming standpoint it will be lots of code.
All of that said dont let me stop you from doing it. I am always up for a challenge but I always warn people that once you get into a challenge you need to ready for what you might encounter.
Feel free to post or send me any network related questions.
