Global Survey Reveals IP Telephony to Overtake PSTN

  • 22 January, 2004 09:49

<p>IR survey of 2800 IT&amp;T managers in Asia, Europe and the US finds rapid growth potential</p>
<p>SYDNEY – 22 January, 2004 - IP telephony (IPT) is steadily replacing legacy PSTN systems in medium-to-large companies, but the split between the two is still fairly even. Call quality, management, and applications that merge voice and data are also important factors in migrating to IPT from a legacy system.</p>
<p>These are just some of the findings of a recent global survey conducted by Australian PROGNOSIS systems and network management software developer Integrated Research (IR – ASX: IRI). The survey polled over 2800 senior IT and telecoms managers, evenly distributed across medium to large enterprises. Approximately 80% of respondents were from North America, with the remainder distributed evenly between Europe and Asia.</p>
<p>IR’s director of IP telephony products Graham Jones says that call quality is the key challenge in convincing companies to switch from their old analogue and digital systems to IP handsets.</p>
<p>“End users are accustomed to PSTN quality and will not settle for less, even with added functionality,” says Jones. “For an end-user, picking up a phone implies getting an instant dial tone, and continued cut-offs or audio quality problems will have users running back to their old phones.”</p>
<p>The survey suggests that most organizations are moving to IP telephony. With 56% of respondents already using an IP telephony system, 26% indicated a trial within 12 months, with a further 18% pointing to a two-year trial date. Key external factors driving IP telephony sales in the next two years appear to be stronger IT spending (strengthening economy), and a perception that IP telephony has come of age (and is now a lower risk).</p>
<p>The survey responses indicated the highest priority business driver for IP telephony is increased value through IP applications (66% response), followed by lower infrastructure costs (64%) and open standards (50%). As expected, Cisco was named the most popular IP telephony platform, with over 52% of respondents currently using – or intending to invest in – a Cisco-based solution. Avaya and Nortel follow suit with 10% and 9% respectively.</p>
<p>Time for real-time
The vast majority (83%) of respondents see real-time management as a critical component of an IP telephony implementation.</p>
<p>“As enterprises deploy IP telephony and integrate voice and data traffic, the new real-time nature of the network infrastructure requires management that is more active,” says Jones. “From initial network readiness assessment through to the first days of testing IP telephony in the lab and on to full deployment to thousands of users, effective real-time management needs to be at the forefront of the evaluation and deployment cycles.”</p>
<p>PROGNOSIS, IR’s IP telephony management software, is the only real-time management solution verified for use with for Cisco’s CallManager IPT platform.</p>
<p>Jones believes that the real-time nature of IP telephony mandates that voice traffic be given priority over data traffic. However, data applications have their own performance requirements. This creates a delicate balancing act, and requires sophisticated tools to manage performance, QoS, traffic policies, configuration, ongoing monitoring and assurance. More importantly, management tools must provide these functionalities in real-time, so the end-user experience can be guaranteed.</p>
<p>This view is backed up by a recent Yankee Group report, “Successful IP Telephony Relies on Real-Time Management” (Yankee Group, 2003). Author and Yankee Group senior analyst George Hamilton says that from the first few days of testing IP telephony in the lab to full deployments of thousands of users, effective real-time management needs to be at the forefront of the evaluation and deployment cycles.</p>
<p>“Choosing the right tool can mean the difference between success and very painful failure,” he says. “Network managers need the capability to monitor the infrastructure and call quality in real-time, generate detailed reports, and effectively manage the growth of the IP telephony infrastructure. With real-time applications such as IP telephony, generating alerts and reports in 15-minute time intervals is not acceptable.”</p>
<p>“PROGNOSIS has proven to help organizations maximize the return on their IP telephony investment and to offer the real-time monitoring and management required for successful IP telephony implementations,” he adds.</p>
<p>According to the Yankee Group, sales of hybrid server-based PBXs and IP PBXs will exceed sales of traditional phone systems by 2006, evidenced by the fact that several traditional TDM vendors have discontinued TDM-only product lines.</p>
