Forum: GNU Radio Planning to do Voice Call project using N210

Dear Community,

I am planning to do voice call and other similar projects using gnuradio
and N210. Voice Call would be between two USPRs N210. I am planning to 
get
two N210 for the projects. I want to ask which block(s) can I use for 
the
purpose and what is the best way to go about it? And whether N210 would 
do
nor not?
