There are two Telecom Providers in Thailand. TOT Corporation (formerly, the Telephone Organization of Thailand) to serve a Domestic voice communications and CAT Corporation (formerly, the Communication Authority of Thailand) serves an International voice communications and Data communications. TOT and CAT are both operators and regulators. They give concessions based on the BTO scheme to winning bidders on selected services. The concessions could be of the same kind due to overlapping roles and authority.
QoS of VoIP in Thailand. No QoS enforced both in terms of latency and accessibility. TOT VoIP domestic service claims to have delay comparable to that of mobile phones. CAT VoIP international service still faces problems about accessibility and latency.
Future Directions (Thailand)
The establishment of the National Telecommunications Committee (NTC) as an independent regulatory body. The Telecommunications Act is in the approval process from the Parliament. Long-term policy goal is set for liberalization.
VoIP in Other SEA Countries
Malaysia, the Philippines, and Singapore has VoIP licenses. Cambodia and Laos are available but still illegal. Cambodian military police have detained 20 foreigners on an alleged IDD bypass scam using an unlicensed IDD gateway. For Vietnam, the Posts and Telematics Ministry has suspended the sales of FPT Telecom’s Internet phone card service. Allow only outbound Internet-based calls from computers to computers and from computers to telephones while prohibiting inbound Internet phone calls.
QoS of VoIP in SEA. Only Singapore has clear QoS results on System Accessibility, Service Activation and Number of complaints. Philippines ask for QoS but does not enforce. Thailand has informal user surveys.
Future of VoIP in SEA
Move toward enterprise VoIP and Private leased-line infrastructure. IP telephony gateway over conventional PABX. More consolidation.
