Session Initiation Protocol (SIP) gives your business the opportunity to unify a multitude of services into a source, creating significant network, equipment and voice cost savings while maintaining a high quality of service to your network.
SIP is a signaling communications protocol that controls voice and video calls over Internet Protocol (IP) networks and can enhance video conferencing, HD voice and data services such as email, text messaging and fax. Call One's SIP Trunking implementation does not require a forklift replacement of existing equipment. In many cases, existing voice equipment can be reused and integrated to maximize value.
Call One's service provides a wide range of disaster recovery initiatives, including primary, secondary and tertiary options, at either the trunk or individual telephone number level. For trunks, redundancy is achieved by traffic failover to any one of our nodes across North America, South America, Asia and Europe. Enterprises electing failover options per telephone number route based on time of day, site availability, traffic flow and more. We also provide deep visibility and control into traffic, via an optional, easy-to-use portal that allows you to route traffic anywhere in the world in the event of a number outage.
Call One helps you evaluate the many SIP Trunking providers and find the ideal one for your enterprise. Enjoy the benefits of mobility, recoverability and scalability — in a single, cost-efficient service. We help you with the contract and billing, too.
