Local Calling Areas:
Local calls are provided through an expanded Intra LATA calling area. Many calls that you were charged in the past as “long distance“ will now become "local calls". This could result in significant savings for your company.

Corridor Calling:
Our corridor calling option allows business customers to call predetermined areas at local calling rates.  If you have high calling within the corridor areas, this may result in significant savings in your long distance charges.

Corporate Calling:
A multi-location business can utilize this plan to make all calls between your business locations at a flat fee, eliminating high usage charges.

Unlimited Local Calling:
Make unlimited local calls with a flat monthly rate.

Unlimited Long Distance:
Make unlimited long distance calls with a flat monthly rate, per line (applies to calls in the continental United States).

Calling Cards:
While outside the office, our calling cards will allow you to make calls as if you were placing your call from the office. All call charges will be billed to your company's monthly invoice.

800 Service:
Allow your customers to call your business at no charge to them. Service is available for calls coming from the U.S. and Canada.
