XO Enterprise SIP enables multi-location businesses to streamline the management and reduce the costs of managing enterprise-wide communications. With enterprise SIP trunking, you can leverage a centralized IP-PBX in one or more primary locations and deliver VoIP services to other branch locations using an existing private network or the XO MPLS IP-VPN service.
XO Enterprise SIP is a centralized solution that is ideal for multi-location businesses with more than 10 locations that are connected to a MPLS-based network. For a SIP Trunking solution that assists companies with fewer locations to maximize their IP-PBX or SBC investments at each location, consider XO SIP Service.
