Patton SN4970/1E24V/EUI Summary

The SmartNode™ 4970 VoIP Gateway offers Enterprises a cost-effective solution to IP-enable their legacy PBX systems. Evolving from Patton’s award winning SmartNode 4940 Series, the next generation SmartNode 4970 Series comes now with IPv6 upgradeable hardware.

Like every SmartNode™, the SN4970 supports every industry-standard CODEC to deliver toll-quality voice on every call. The Unified Communications Agent™ (UCA) provides any-to-any multi-path switching (simultaneous SIP, H.323, ISDN, and POTS calls with routing and conversion between TDM/PSTN and IP/Ethernet networks—plus T.38 and SuperG3 FAX). VoIP-over-VPN with voice encryption provides secure voice and data via IPsec with AES/DES strong encryption and automated keying via Internet Key Exchange (IKE). In addition, advanced call-router functionality includes least-cost call routing with flexible dialed-number plan support.

The SmartNode survivability suite offers PSTN fallback to ensure business continuity in case the IP network fails. Furthermore, SmartNode’s unique high-precision clock delivers first-line IP telephony service in demanding ISDN and DECT environments with reliable FAX and modem performance. In addition, SmartNode delivers a smooth transition to VoIP with strong number portability support accepting incoming calls from the PSTN throughout the VoIP service provider's number porting process.
