The SmartNode™ 4990A VoIP Integrated Access Device for 15-to-120 VoIP calls lets enterprises graduate to All-IP at their own pace. The one-box solution includes a built-in G.SHDSL-EFM/ATM, VDSL/ADSL, fiber, or X.21 WAN interface for broadband access. The integrated WAN-access options reduce CPE costs, simplify network architecture, and accelerate service deployment. A SIP back-to-back user agent provides SIP normalization that ensures interoperability between any customer PBX and any provider softswitch on the market. Built on a platform that is ready to support IPv6, the SN4990A provides secure TLS and SRTP encryption* while supporting all the industry-standard CODECs for toll-quality voice on every call.
The SN4990A delivers secure, prioritized unified communications with one to four T1/E1/PRI and two 10/100/1000 Ethernet ports—plus broadband access—in a single box. An optional third 10/100 Ethernet port may connect to an out-of-band IP management network, or—for enhanced survivability—provide a redundant Ethernet connection to the (same or alternate) service provider.
