I have tried out several VOIP service suppliers recently and some were a disaster ! but then I found YAY---strange name I know but their service was brilliant and call quality and features were excellent but the best bit was customer support. Replies to all my questions were answered very quickly and meaningful by very polite and knowledgeable staff sorting out extremely comprehensive dashboard settings that were at the start not totally obvious( to me). So I have no hesitation in recommending them especially as they have a 14 day no holds barred trial totally free so you can experience their service for your self.
