The customer only paid for their maximum concurrent calls, not 46 like they did with their PRIs! No new equipment, no new lines installed. $250 install fee, and cost for additional ShoreTel licenses This solution was implemented within hours instead of weeks This customer is saving approx. $3,700/month or $44,000/year! What impact does this have on your budget if you have an extra $44,000?!?
