ENTERPRISE SIP TRUNKING
Cut costs and simplify IT management. Integrate voice, video and data onto a single circuit.
Whether you are transitioning from TDM to VoIP or simply want to cut costs, Cellulax Enterprise SIP not only provides significant cost savings and simplifies IT management, but offers failproof backup and disaster recovery to ensure that your business is running 24/7/365.
Enterprise SIP allows you to easily and seamlessly replace your traditional T-1 based PSTN to a cloud-based solution while using your existing phone systems. Calls are routed through the Internet rather than the PSTN, eliminating the need for costly dedicated voice T-1/PRI circuits and the expensive telecom services that go along with them.
