Session Initiation Protocol Trunking Adoption in Asia-Pacific

Session Initiation Protocol Trunking Adoption in Asia-Pacific

Countries in the Asia-Pacific region have varied but low awareness levels of session initiation protocol (SIP) trunk technology, which has led to low adoption levels across the region when compared with other regions such as North America and Europe.

Australia and New Zealand have relatively higher adoption of SIP trunks, Singapore and Hong Kong have medium levels, while China and Malaysia have low adoption levels but a high potential market for the technology.

Although SIP trunking is not new in the region, very few providers are proactively offering it. Other providers offer it to customers as a retention strategy.

Traditional telephony systems and security remain the top constraining factor for the adoption of SIP trunking in the region.

SIP trunking has potential to save more than 􂀀% on telecommunication costs over ISDN lines and offers various benefits that include scalability, number portability, and support to mobility, as well as delivers better management console and capability to IT managers.

Third-party vendor solutions that offer enterprise session border control (E-SBC) help solve the problem of security by providing an embedded firewall. E-SBC also allows businesses to take one step at a time while transitioning from an ISDN PRI/BRI line to a SIP trunk.
