A survey of 300 large enterprises across Europe, published today, has found that 73% of IT directors are still worried about basic quality and reliability of Voice over IP (VoIP), despite a strong industry trend towards converging voice and data traffic onto a single data network.
The research, by Vanson Bourne on behalf of Compuware, found that half of the large companies surveyed currently have a class of service (CoS) enabled wide area network (Wan) - which includes MPLS, IP-VPN or meshed technology. The other half have a traditional (frame relay or leased line) Wan.
Forty seven percent of the companies with a traditional Wan plan to migrate to a CoS enabled Wan over the next two years.
The research found that approximately a third (39%) of companies do not fully prepare for the impact on the network of introducing new applications such as VoIP.
In addition, 72% of the IT directors surveyed use basic measures such as monitoring overall network utilisation to check that applications are working, rather than examining the individual performance of each application.
Michael Allen, global director of performance solutions at Compuware, said the concerns over quality and reliability were “not entirely unexpected”.
“It's like driving a new car before the manufacturer has checked that all the components are fitted together properly and the safety checks are completed. Businesses must profile performance prior to deployment otherwise they have no way of knowing whether there will be negative side effects due to factors such as network design or application conflicts,” said Allen.
Analyst firm Frost & Sullivan is one of many predicting that VoIP will account for around three-quarters of the world’s voice traffic by next year.
