Call quality issues for VoIP is getting attention from some of the biggies in the industry. Apparent Networks and Nortel Networks have signed a deal to look into quality issues. One project will result in software which Nortel intends to embed in their VoIP products. With such software system users will be able to trace the source of potential quality problems. [via eWeek] The premise is that call quality is subject to many factors, and not necessarily caused by faulty VoIP hardware. Since Nortel is a hardware vendor, such software would help them remotely track customer problems and thus both reduce support costs and result in happier customers sooner.
