PRI and SIP Trunking

Fiber-optic voice services


Cost savings

Having a PRI provides a cost-efficient alternative to terminating individual analog trunks into a PBX system.

Digital vs. analog technology

Our PRI uses digital rather than analog technology between the PSTN network and your premises for better security and fault tolerance.

Standard interface

The PRI interface is a worldwide standard supported by all PBX manufacturers. It includes voice channels as well as the D channel for call set-up and tear-down functionality.

Enhanced capability

Our PRI has the capability to include two-way trunks and Caller ID (name/number) notification. It also reduces call set-up times by utilizing D channel out of band signaling across the PSTN network.

SIP Trunking

Leverage unused bandwidth

With voice and data converged on one network, bandwidth can be dynamically allocated to allow for increased or decreased usage in either direction. For example, you can temporarily allocate bandwidth to support batch jobs during down times to reduce excess, idle capacity.

Maximize existing investments

SIP Trunking can support existing on-premises equipment.

Consolidate resources

Converging voice and data on the same network means there’s no need to manage or pay for separate access.

Increase traffic

SIP Trunking uses compression technology to pump more voice traffic on the same size pipe.
