Voipgo vs Aircall

Here's my story: I've used this service for 2 weeks now.  It started off shaky.  My VOIP did not work at first, so I contacted online help.  After a little while they informed me that it looked like I was being sent onto an American system or something like that.  They told me to wait for an e-mail saying that it had been fixed.  So I waited, and nothing came.  So I tried to use it the next day and it worked. But, the sound quality was horrible.  Tinny, with an echo.  I contacted customer service, and they recommended I not use a wireless connection.  Well that wasn't the problem.  So I submitted a ticket and got no recommendations from Voipgo technical support on how to improve the sound. Then I realized that the soft phone available for download on the Voipgo site was the X-Lite 3...there is an X-Lite 4 now.  So I downloaded that and everything is great. So I contacted online help and told them what I did and they credited me 5 dollars for being helpful. Online help is available most of the time, the price is a very reasonable 17.95 a month for unlimited incoming/outoing calls, and if you're on both lines the third call coming in will ring busy.  (Busy signal is cheesy sounding but not a big deal.)  I needed a busy signal for my business which is why I chose Voipgo and I am glad I did.
