[Asterisk-biz] VOIP Services State/Federal Licensing requirements

[Asterisk VoIP]

Any one can help me to find out is there and legal State/Federal
licensing requirements to start VOIP services? My company would like
offer VOIP services to our existing customer base just wondering
before going any further do we need to get any legal licensing from
State/Federal authority to offer commercial VOIP
services or we can offer under our existing LLC status? 

Thanks,
John.
