Review your plan, user count, addresses and requirements. One user means one named person licensed for an account/extension; numbers and concurrent call paths are confirmed separately. Every final order must itemize base service, standard implementation, separately purchased phones, accepted add-ons, applicable taxes and actual telecom/regulatory charges, exact due now, covered dates and renewal schedule.
Do not submit PHI, payment-card data or porting PINs. Equipment quotes require confirmation of compatible PoE capacity or separately priced power adapters/injectors.
