NEC UNIVERGE Product Configuration
How We Did It
All necessary components of a typical NEC UNIVERGE unified communications installation were tested. This included the SV7000 IP-PBX server, the UM8500 release 3.0.1 messaging component, the MA4000 Web-based management application, the OW5000 presence application, the UA5200 attendant console solution, the MC530 cell phone application, the UC700 desktop client, the DT 300-700 series desktop terminals and the Dterm SP30 softphone.
Also tested was the IP Messaging components of the UM8500, including both the Microsoft Exchange and the Active Voice (AV) version 18.104.22.168 UCS12 (active suites version). Both versions were evaluated separately in a redundant server configuration using Microsoft Cluster Server (MSCS) version 1.0 which is included in Microsoft Server 2003. Part of these tests included alternately failing the servers and checking the impact of this shut-down on voicemail availability and its redundancy.
UC client endpoint compatibility between Microsoft’s Office Communicator and NEC’s own instant messaging application was verified. SIP endpoint tests were conducted and they verified that latency and voice quality were within acceptable standards for voice telephony. MOS 4.0 was our minimum, but the NEC IP phones actually achieved better quality at a 4.4 MOS score. These tests, as well as SIP signaling analysis and verification of traffic encryption, were conducted using the ClearSight Analyzer, a distributed protocol and traffic analyzer from ClearSight Networks (www.clearsightnet.com). Voice quality assessment was evaluated by capturing live traffic from the network and post capture analysis processed through the ClearSight Analyzer.
SIP traffic load tests (which emulated endpoints) were conducted using the Empirix (www.empirix.com) and Touchstone’s (www.touchstone-inc.com), WinSIP 3.0. An impressive 32,369 busy hour call attempts with 1,000 concurrent users was

Security scans including open port scans, protocol interaction with mutated traffic, common vulnerability exploit tests, denial of service and SIP server torture tests were conducted using Miercom’s own testing suite combined with a Mu Dynamics (www.MuDynamics.com) Mu-4000 Security Analyzer. The vulnerability scans were run first to provide information that could be used in subsequent compound or complex attacks.
