I would like to start up VOIP communication business (from phone to phone not computer to phone ). I have studied little bit about VOIP. I do not have much understanding of it. I would appreciate if someone could tell me software and hardware requirements for VOIP.
I’m working on comparing the productivities and performances of voIP and voATM and I need the simulation programs for voATM and voIP (and source codes if available) if you have , or know where to find it please reply me…
