Difference between monthly fee and monthly commitment

A Monthly Fee is a monthly recurring charge that you will be billed each month for your domestic, direct-dialed long distance (excluding usage charges, taxes, surcharges and fees).

A Monthly Commitment is a predetermined amount of long distance dollar revenue you commit to spend each month. The revenue may result from state-to-state, in-state and international usage charges (excluding taxes, surcharges and fees). If you spend less than the Monthly Commitment in a given month you will be still be billed the full Monthly Commitment amount for that month.
