My company is evaluating significantly expanding the use of Grasshopper. There is one very important feature that is missing which is gating expanded use. A feature that is required is a switch which enables a 'wifi only' mode on an extension by extension basis. This mode would change the current behavior so that Grasshopper would never switch from wifi to a regular phone connection even if the party is unavailable by wifi. Is this feature under consideration by Grasshopper? If so, is there a rollout in plan in the neat future?
