Hi, I am Zeeshan Awan, I have three years of experience in voip development and services.
I have worked on a similar setup for a private limited company. I am available for 20 hours a week, and would like to work with you on this project. I also have an online demo available for a small VOIP bussiness calling card, pc2phone, phone2phone, callback etc. thats setup using asterisk and a2billing, so if you are interested I can provide you with information regarding that as well. I am looking forward to an interview and working with you.
warm regards,
Zeeshan Awan.
