Featuring hardware-accelerated voice encryption and software optimized for security processing, the SmartNode™ 4562 makes VoIP accessible to organizations that have been missing out on the cost-saving benefits of Internet telephony because of security concerns.
The SmartNode 4562 securely integrates remote or branch offices into the corporate voice and data network using state-of-the-art ISDN VoIP technology. With all inter office traffic secured by IPsec/AES strong encryption and Internet Key Exchange (IKE), users can replace expensive leased lines with low-cost Internet access. All RTP, SIP signaling and data communication are transported through the IPsec VPN tunnel, protecting them from wiretapping, sniffing, or attacks. Patton’s exclusive QoS features, including advanced traffic shaping, VLAN tagging, 802.1p/q and DSCP enforce toll-quality, uninterrupted voice, also inside the secure VPN tunnel.
Industry-leading call routing features include hard and soft communication fallback to the ISDN breakout port in the event of failure. A complete set of industry standard codecs deliver toll-quality voice while T.38 fax, fax bypass, and modem bypass features ensure that no services are interrupted when migrating to VoIP.
