PSU saves time and money with unified communications

SINGAPORE, 22 SEPTEMBER 2009 - 3Com, a provider of secure, converged networking solutions on a global scale to businesses of all sizes, has successfully simplified communications at Thailand's Prince of Songkla University (PSU).

The university is using 3Com's pure VoIP system that covers PSU's five campuses and more than 8,000 telephone terminals. The deployment of 3Com's network has translated into significant time and cost savings for the university. Unified communications has also delivered other benefits such as increasing productivity and freedom from maintaining multiple networks.

Search for a cost-effective solution

Established in 1967, Prince of Songkla University (PSU) has its main campus in Hat Yai and four sub-campuses in the Pattani, Phuket, Suratthani and Trang districts. All these campuses are located across the south of Thailand.

According to 3Com, PSU was searching for a high-quality communications system that could cost-effectively connect the university's 30,000 students and 8,000 employees. The university realised that using conventional telephone lines put a strain on its communications budget.

Initially, it tried to monitor the frequency and lengths of these phone calls but soon gave up as important calls tended to be fairly extensive. It then began searching for a more cost-effective solution and after evaluating other solutions in the market, decided to deploy the latest VoIP (voice over IP) technology from 3Com.

Kosit Chitpong, head of telecommunication services department, PSU Computer Center, said the university also wanted a solution that could support advanced communication services, including voice, e-mail, video conferencing and fax in an easily manageable way.

Improved efficiency with 3Com's VoIP

All the requirements were met by 3Com that was appreciated for delivering great value, reliability and quality. PSU reconfigured its private branch exchange (PBX) in all its campuses and modified the interconnections between all existing PBXs from conventional telephone links to four VoIP gateways. The officials said these gateways are powered by two redundant 3Com VCX SIP servers at the main Hat Yai campus.

The university followed a different approach for its Trang campus by upgrading its old and limited capacity PBX to a full VoIP system with local IP phones. PSU has now transformed its Trang campus into the first fully VoIP network in Thailand.

Chitpong said the deployment has resulted in significant savings for PSU and the university estimates savings of about three million baht (US$86,000) in the Trang campus alone. Besides cost savings, PSU is also able to manage voice communications, e-mail, fax and IP conferencing through a single network.

PSU is very happy with the services provided by 3Com and have engaged them for ongoing support and services. 3Com will also help PSU add more advanced applications to support the communications needs of the university.
