FAQ:
Q> Is WiFive Phone free, or is it an evaluation version?
A> There is no charge for individual users to use WiFive Phone.
However, there is a "beep" sound every 10 secs after the first 7 minutes of conversation, because the WiFive Phone uses commercial codecs such as G.723.1 and G.729A.
In the case of enterprise- or carrier-grade customers, you can buy WiFive phone licenses and you will not hear the "beep" sound anymore.
