What is the most cost effective yet reliable cloud VOIP platform?
We are currently using AVAYA voip system in my firm but the licence costs are extortionate as well as the maintainence costs. Im thinking a clouded voip system would be the answer but not sure what is a reliable but cost effective option that has stood the test of time with as little downtime as possible. I work for a stockbrokers so it would be an uproar of our phones went down so reliability is key. Any options would be greatly appreciated. Oh and im in the UK but I guess with clouded voip it doesnt matter where you are but a place with 24hr support would be good.
