Abstract

Lucent Technologies, Inc. commissioned The Tolly Group to evaluate its MultiVoice VoIP Solution that includes MAX TNT WAN Access Switches and a Lucent MultiVoice Access Manager. Lucent also commissioned The Tolly Group to test Cisco Systems, Inc. AS5300/Voice Gateway devices with a Cisco 3640 Gatekeeper. Competitive tests were conducted to determine the average percent of call completion every six hours for a total of up to 72 hours across both the Lucent and the Cisco gateways. Engineers also conducted tests measuring the average PSQM as defined by the ITU for each device when using G.711, G.729 or G.729a vocoders.
