Announcing Skype For Business Cloud Connector Edition version 2.0

Hi Ghazi Boufaden we see the pattern toward 1:6 or even, in some cases, 1:4. The reason once you migrate to SfB many calls are converted to VoIP calls that don't require PSTN network. I recommend look at current tepephony statistic, predict how many calls will be VoIP (if migration from a pure PSTN deployement) and make the desicion. Let me know if you want to sync offline.
