Had 3Jam which had many of the same call blocking features, alas, they sold and were not renewing accounts.  Tried the Magic Jack Plus which was a childs toy.  In addition, Magicjack does not allow anonymous incoming calls and play an ad prior to the call reject message.  Sure, I don't normally want anonymous incoming calls either but I would like the choice.  Magic Jack also blocks calls to certain areas where they have failed to nogotiate interconnect agreements so you never know if your call will work or not.
 placed my order for Voipo on January 6th and requested my Google Voice number be ported to that account, finally got the Letter Of Authorization and other documents needed by Voipo to them and was told that my number had been submitted for porting.  I did receive a temporary virtual number for incoming calls which I tested forwarding to my cell phone and the Magic Jack line.  One surprise was a one minute call I placed to the virtual number from my AT&T number and forwarded to the Magic Jack number where I answered and said testing one, two three and hung up was billed as 361 minutes.  I submitted a trouble ticket explaining this was a one minute call and there were several right after that to and from the same numbers and this could not be accurate.  The response was that perhaps the equipment did not disconnect correctly and I should always be sure to disconnect???  That was a frustrating response as how could I have made several additional calls within a few minutes without disconnecting.  I hope this is only a one time glitch as even though they say the service is unlimited there is an excessive usage cap of 5000 minutes as stated in their terms of service. 
As mentioned earlier, their call blocking features are robust and work as described.  I am deluged by telemarketers spoofing numbers and all of the available blocks provided by Voipo work perfectly.
The price is great, custimer service located in the United States.
