Are Wireless Carriers Like Blocking Free Conference Calls?
I had an interesting experience the morning trying to call into FreeConferenceCall on my mobile phone.  I tried calling in about a dozen times and received a busy signal only dialing a number in Arizona.  A few weeks ago I had the same experience dialing a number in Iowa.  Same thing a busy signal.  Are carriers blocking calls to FreeConferenceCall?  Why would they do this?  
I suspect this could be the case because in both circumstances I made the same call from my home line and the call went through.  The next time you get a busy signal trying to dial into a conference call let us know.  
Our tweet was answered and apparently our assumption was correct.  The million dollar question is which carriers?  T-Mobile yes but what about Verizon, AT&T and Sprint?  
@DeadZones Yes, some providers block conferences. Call our Customer Care team and they can always provide you a back up number.
