XO SIP Service

XO SIP Service* is a converged solution that offers IP-PBX customers direct IP access to the XO private, OC-192 IP network for data and voice communications. XO SIP offers the performance of business-class VoIP without the costly, bandwidth-consuming protocol conversion of traditional T-1s and other access technologies.

With XO SIP Service, companies can maximize the performance of their IP-PBX. SIP provides the direct connection to the XO IP network and eliminates the costs associated with the purchase, support and maintenance of media gateways while reducing the recurring costs of separate Public Switched Telephone Network and data circuits.

Dynamic Bandwidth Allocation enables voice traffic to always take priority, enabling businesses to maximize the full IP circuit to support data traffic when voice lines are idle. With a single circuit used for both voice and data, you no longer need to account for voice and data paths separately.
