IP Voice 8XX Origination

Your Ideal IP Voice Origination Provider

CenturyLink™'s expertise in broadband, IP, and telephony make CenturyLink the ideal company to provide you with Internet Protocol (IP) 8XX origination services. CenturyLink's IP Voice 8XX Origination service is a cost-effective way for service providers to receive inbound 8XX (toll free) PSTN originated calls in IP format. CenturyLink offers a full featured IP toll-free service across an OC-192 network with over 1,700 access points and over 16,000 routes.

How It Works

Traditionally, carriers order 8XX service and receive calls generated to the PSTN from their customers in TDM format. The CenturyLink^™ IP Voice 8XX Origination service allows those PSTN-generated calls to be handed off to the carrier or enhanced service provider in SIP (VoIP) protocol. Existing customers migrating from TDM to IP and new IP-based customers can take advantage of packet-based voice with a single internet access trunk, or via the public Internet eliminating the expense and management of separate TDM-based access trunks.
