Agilent Offers VoIP Service Assurance for SIP Push-to-Talk

Agilent Technologies announced an OSS analysis system for monitoring the voice quality of wireless SIP-based push-to-talk (PTT) services. Push-to-talk enables wireless users to connect in a "walkie-talkie" mode with other individuals or with groups of mobile phone users at the push of a button. There is increasing interest in using SIP to establish and maintain the connection between PTT-enabled handsets. The new Agilent OSS NgN Analysis System enables VoIP service providers to monitor, troubleshoot and identify call quality and failure issues over such connections. Packet protocols supported by NgN Analysis System include SIP, MGCP, H.323, NCS, TGCP, IPDC, SS7 and RADIUS, as well as leading proprietary protocols such as Q.931/RUDP.
