This enterprise VoIP Router IP-enables any legacy digital and/or analog voice/fax system for up to 8 to 24 concurrent VoIP /T.38 fax calls. The SN4660 connects ISDN-PBX, analog fax/phonesóeven audio-intercom systemsówith IP telephony and the PSTN.

The SmartNode™ 4660 VoIP Gateway Router offers flexible combinations of ISDN BRI, analog FXS/FXO, and Ethernet/IP interfaces to deliver a unique solution allowing the Enterprise to IP-enable legacy ISDN-PBX and analog phone/fax/answering machine and audio-intercom systems.

Providing 4 Ethernet, 2 to 8 BRIs, up to 4 FXS and up to 4 FXO ports, the SN4660 VoIP Router inter-connects any Ethernet switch, ISDN PBX, analog equipment or IP-data network to support 8 to 24 simultaneous VoIP calls using SIP, FXS/FXO or BRI signaling. The 10/100 Ethernet uplink provides seamless WAN access via any existing cable, ADSL, VDSL, EFM, or fiber-optic modem.

Like every SmartNode™, the SN4660 supports every industry-standard CODEC to deliver toll-quality voice on every call. Adding session border controller capabilities, the SN4660 VoIP Router includes IP transcoding for up to 12 SIP channels. 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 combines PSTN fallback, SIP Registrar and IP-link redundancy to ensure business continuity if the IP network fails. Patton’s DownStreamQoS™ delivers the advantage of clear, uninterrupted voice-and-data communication. 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.
