Atlantic Telecom vs RingCentral

Im a total newbie when it comes to using voip, but i did a lot of reading on the subject.  After getting my last phone bill (yes i like to talk) i decided to take the plunge and signed up with atlantic telecom.  The sign up process only took about 5 minutes in all and i got all my instructions by email soon after. My box arrived after 3 days (i was told up to 7) and was very pleased with myself after figuring out what to do with the cables. - yes im a female and know nothing about computers and the like.  Anyway to cut a long story short i have to say WOW.  The call quality is very very good and i love the features i get including voicemail to email - very neat! For $19.99 a month i get unlimited USA / Canada & Europe calls (my mothers in england) and i am just so impressed with the whole thing.  I recently found out i can even use my laptop with a phone called x-phone or something like that - its pretty cool too. I have never used anyone else for voip, but im glad i chose the company i did - top marks all around. My account management features are really easy to use and i can log in at anytime to see anything i need to. I kept my phone number for FREE too, no porting. There was no small print or catches that i found with other providers - another big plus for me. With this atlantic telecom, unlimited is unlimited, not limited like vonage
