The VX gateway is a fully integrated multi-service voice switch that provides high-performance secure Voice over IP (VoIP) communications for the enterprise OCS deployments. It secures both signaling and the media through standards protocol. The in-built firewall capabilities further extend the security by protecting the networks from denial of service attacks.

The VX gateway interoperates with all leading PBX and IP-PBX vendor protocols, offering rapid deployment, easy installation, minimal maintenance, and high security.

A single appliance simplifies OCS deployments at the branch office. It provides encryption using SRTP and TLS, translates SIP over TCP/UDP to SIP over TLS, connects clients outside the network with internal users using ICE components to enable NAT traversal, and provides PSTN connectivity.  See the illustration below.
