Technology has been driving market demand and reducing the investment in POTS significantly in recent years. As a result, both Windstream Enterprise and our partners are shifting our investments and support to other areas that offer greater potential and growth.

Effective December 1, Windstream Enterprise will no longer accept POTS orders for new end-users. Please note, we will continue to support changes and disconnects for existing users.

We apologize for any inconvenience and encourage you to pursue our alternate technologies such as Dynamic IP Analog Handoff or Online Fax solutions.

For more details, contact your Windstream Enterprise Resale account representative.
