So, what’s new?
CTA affiliate in-country partnerships further extend its extensive portfolio of carrier relationships that enable it to offer full PSTN replacement services in over 20 countries and local DID (Direct Inward Dial) number support in more than 100 countries.
Specifically, this new capability provides multinational customers with the new option to select a local DID (Direct Inward Dial) number, for the city in which they have an office. Over a dozen city dial locations in China are supported, including the major international business hubs and a majority of cities in China.
Isn’t that already possible, using an in-country gateway?
Traditionally, due to the lack of local PSTN interconnect options from international carriers and most cloud voice providers, companies have been forced to rely upon the combination of costly locally hosted gateway devices and VPNs to connect China-based personnel and their local contacts.
This older, compromise solution is complex and costly to manage, and is a potential single point of failure. It only enables the local break-out of domestic calls to/from international destinations onto China’s public telephone network. International VoIP calls are not supported in China, which further limits the call scenarios supported by a gateway solution.
What are the benefits of the solution?
Any inbound call that originates in China is onward-connected, without the call leaving Chinese jurisdiction. Similarly, outbound calls from a China-based user to a domestic PSTN number will remain in China, with local caller ID correctly presented. Most importantly, and often a key customer requirement, calls to local emergency services numbers are also supported: including police @110; fire @119; ambulance @120.
What type of DIDs are available?
The number ranges are geography-specific, corresponding to the main business hubs and Free Trade Zones in China, including from Chengdu in the west, Guangzhou in the south, Shenyang in the north and Ningbo in the east.
Are there any further considerations when planning to add users or numbers for China?
We will provide end-to-end hosted solution and dedicated SBC for customers who order more than 1,000 numbers in China. For smaller demand, we will provide an on-premises solution which may share virtual PBX with other customers or dedicated SBC. As such, it’s recommended that you review the potential rollout schedule to ensure that the available capacity is ready to accommodate the required system size. Note that only customers with users that are physically located and registered in China can take advantage of these services.
