GAITHERSBURG, MARYLAND, USA: Patton Electronics—US manufacturer of UC, cloud, and IoT enabling solutions for carrier, enterprise and industrial networks—announces the new 200-call SmartNode 5500 enterprise session border controller (eSBC).

With the SN5500, Patton has more than tripled the SIP-to-SIP calling capacity of the popular SN5300 eSBC

The new eSBC aligns squarely with the VoIP calling requirements of organizations that employ over 600 and up to 2,000 people and require secure and reliable connectivity to a SIP-trunk or hosted-PBX service.

The SN5500 is equipped with WAN-access ports that enable redundant wired or wireless network connections that ensure business continuity by providing IP-link failover for system survivability. 

With a built-in local SIP registrar, the SmartNode self-learns the session-control data for such SIP endpoint devices as SIP phones, softphones or unified communications (UC) clients. This intelligent eSBC feature eliminates the need for any re-configuration of the end-point, service, or network settings that would otherwise be required to maintain call control in a failover scenario.

In the event of a failure in the provider network or service chain—for any reason—the SmartNode automatically delivers traffic over an alternate path. Whenever the access network, SIP trunk, or hosted service is down, this failover mechanism sustains E-911 service and station-to-station call capability, as well as inbound and outbound calls.
The eSBC can provide CODEC transcoding for up to 16 concurrent calls, offering bandwidth management and WAN optimization for remote and branch-office calls.

TLS/SRTP encryption for voice and signaling data, as well as firewall services, means the SmartNode provides converged voice-and-data security services at the network edge. These services protect the enterprise LAN as well as the service-provider network from such security threats as snooping, hacking, toll fraud, and denial-of-service attacks.

The SN5500 delivers superior performance for reliable fax service while supporting all the essential VoIP and fax protocols, including SIPv2, SIPv2 over TLS, T.38, G.722 HD voice, RTP security with SRTP, fax and modem bypass, and DTMF relay.

Patton was recently profiled—with high marks—in the Gartner Group eSBC Market Guide, published last week.
