Sorenson Communications provides a video relay service for Deaf people to make phone calls. Along with this free service with use of interpreters direct calls can be made to other VPs as well as webcams on PCs without going through the relay. There is no IP address reqd because they assign phone numbers. They have VP100 and a newer VP200 and their own software. I basically need some software with video capability that i can just put in a phone number and call. I am looking for something I don't have to pay for.
