Voice Carry Over Setup

[Loudcloud]

For those who use the IP relay system; I'm hearing impaired w/ little hearing residual and can talk well. What is the best way to set up a system to use the IP relay service using VCO w/ Blackberry and how? Also, which kind of relay services and why? What ways do you have setup for incoming calls? I cannot imagine callers calling me will have to use 800# to reach me, that's absurd! I welcome everyone inputs, suggestion or ideas.

Thanks!
