SIP Trunking
The FlexTEL Enterprise IP Trunking service allows businesses with IP PBXs to extend the benefits of Voice over IP (VoIP) convergence from their LAN to the WAN and the Public Switched Telephone Network (PSTN). It virtually eliminates the need for expensive TDM gateways and trunks, helps to increase network efficiencies and cost-savings by converging voice and data traffic on your WAN, and retains all the features and services of your existing TDM connections. In addition to these benefits, the Enterprise IP Trunking service is specifically designed to meet the needs of distributed enterprises, allowing you to connect multiple locations while maintaining local telephone numbers, calling plans and 911 services.
Business Continuity Support
Business continuity is supported by specialized features for disaster recovery and mobility. Since the mobility features are provided at the network level, calls may be routed to alternate locations or devices in the event that IP PBX service is interrupted.
Enhanced Performance and Network Reliability
Our Enterprise IP Trunking service has diversity and redundancy built into the physical network and the IP service infrastructure to enhance reliability and performance. All IP traffic remains on FlexTEL's premium IP backbone until it reaches the PSTN, which helps improve overall service quality and eases problem resolution.
