When it comes to anything telephone related, I am your guru.I have more than 20 years experience in the telephone industry in almost every permutation out there -- call centers? SMS? Smart phone development? Calling cards? International routing? IVR? PBX? I've done it all. I've worked on projects from payphones to modems to 10 million PIN calling card systems.I have the variety of programming skills (C/C++/Java/C#), along with the support systems (PHP and SQL) to make your telephony project go beyond the average and make it succeed.
