Our toll-free service extends your organization's reach and keeps things simple. You pay just one flat rate for calls from the 50 U.S. states, U.S. territories and Canada.

Highlights include:

• Keep your existing toll-free number or select a new one at no additional charge
• Customize routing options based on call origination, date and time received or percentage called to different destinations
• Accept or block incoming toll-free calls from specific area codes or exchanges

Our business continuity options are designed to keep your organization running smoothly, even during peak calling periods and extra-heavy calling days. The options range from having the service automatically reroute inbound calls to full-path diversity.
 

Highlights include:

• Automatic rerouting of inbound calls to any destination when all channels (or call paths) in the trunk group are in use
• A primary and secondary fiber connection between your organization and our network with no single point of failure
• Redundant voice gateway equipment

Our load-balancing options enable you to balance your trunking resources more efficiently by distributing incoming voice traffic across multiple trunks. We also offer a variety of routing options—including circular, weighted percentage, most idle and least idle—to give you the flexibility to best manage traffic according to your specific needs.
 

Highlights include:

• Manage peak usage across different locations and time zones
• Gain more granular control over network utilization by load balancing your trunks
• Route calls to available trunks if a trunk becomes unavailable
