XO SIP service provides IP-PBX customers direct IP access to XO’s private OC-192 IP network. It is a low cost, low bandwidth consuming protocol conversion that offers the performance of business-class VoIP, unlike the traditional T-1s and other equipment.
Providing a direct connection to the XO IP network reduces recurring costs of the PSTN and data circuits, as well as eliminates the costs associated with the purchase, support, and maintenance of media gateways.
Voice traffic is prioritized though XO’s Dynamic Bandwidth Allocation. This allows businesses to maximize the full IP circuit, and helps them ensure that when voice lines are idle, data traffic is supported. The selection of port speeds and scaled calling plans to fit the needs of each customer are also available without the hassle of per line fees.
