XO Communications has launched XO IP Flex, XO SIP and the industry’s first bandwidth-based pricing for converged IP services. XO’s innovative pricing eliminates pricing based on the number of voice lines. Customers simply select XO IP Flex or XO SIP and then choose an IP port speed from 1.5 to 45 Mbps, a calling plan and any additional features. Customers pay nothing for incremental lines or voice channels provisioned within the port speed they have with their service.
