Sonus'  VX1800 is the clear choice for enterprises that want to integrate unified communications solutions into existing voice networks and legacy PBX systems.

Flexibility that Drives Greater Cost Savings

The VX1800 provides a lower cost solution for VoIP and unified communications by enabling enterprises to consolidate or reduce existing voice network infrastructure. With support for enterprise mobility and SIP-WiFi devices, the VX1800 can also help reduce on-campus cellular service costs.

Security with Scalability

The VX1800's optional hardware-based Security Acceleration Module provides scalable, high-performance IPSEC, SRTP & TLS encryption for voice over IP communications. With up to 24 T1/E1 ports the VX1800 has the scalability for the largest enterprise sites. Redundant AC power provides the reliability required at these sites.

Bandwidth Savings

In addition to a wide range of voice compression technologies, the VX1800 uses BESTflow™ technology to enable voice calls to be carried over the WAN while utilizing less than half the bandwidth of traditional VoIP switches.
