China has strict telecommunication restrictions in place surrounding the use of VoIP, which can lead to reachability issues. This is a universal approach and not exclusive to Aircall and our carriers.
When using Chinese numbers for calls, or dialling to Chinese numbers, it is best to take note of some important points:
-
Chinese numbers can only be used for inbound calls. They are not able to be used for outbound calling purposes.
-
Chinese numbers can only be called from an international, non-Chinese number. Any inbound calls with a Chinese caller ID will fail.
-
Strict spam monitoring and general restrictions on VoIP in China means that numbers involved in any calls under three minutes have a high probability of being blocked. Try to ensure an average duration of three minutes or more.
-
No unsolicited marketing calls.
-
If you have a high-volume of unanswered outbound calls, your calls will be blocked.
-
Do not make calls from modified, spoofed, or restricted origination numbers.
-
Avoid high volumes of repeated calls from the same origin number within one hour.
-
Do not use a toll-free number as they will be blocked.
- Outbound calls to Chinese numbers are not guaranteed to be connected.
⚠️ Please note that Aircall does not offer Porting or Purchase of Chinese numbers.
⚠️ Please note: As of November 30th 2023, due to an industry-wide impact, Aircall is discontinuing call services to Mainland China, effective immediately. Unfortunately at this time our business, and many others in the industry, no longer have the ability to offer outbound calling to China based on China's stringent calling restrictions.
