Need more Extensions / Base Station Capacity

I recently moved to OOMA Office from a traditional VOIP Provider. Our business has grown significantly and I now find myself unable to add enough extensions for my new employees.

Is there a way to exceed the current limits on base stations or extensions on OOMA Office> Can I participate in a beta program to test this expansion? Does anyone have an alternative solution to this problem?

This is the residential forum. There is a separate forum for Ooma Office.
