The potential for cloud communications providers to impact the telephony cost structure has been a point of discussion for the last five years, further illustrated by the $10 Zoom Phone offer shown at Zoomtopia. As the cloud deployment model emerged, I predicted a 50%-75% decline in the cost of business telephony, and now it appears that we are reaching a $5/month subscription for individual phone licenses that bundles video meeting and telephony. But how soon will telephony costs be a sub-segment of overall communications costs?
