International Calls to China

International Calling Outbound to China: Can you call China?

Due to regulations implemented by the country of China in 2022, it is increasingly difficult to guarantee call completion to Chinese phone numbers. Carriers are regularly and globally blocked at the countries' firewall for violating their strict regulations and guidelines.

China implements IP blocking for trunks with carriers that violate any of the following:

• A less than 3 minute phone call duration average
• Any unsolicited marketing calls
• High volume of repeated calls (to > from) in the same rolling hour
• High volume of unanswered calls
• Spoofed calls

Due to these restrictions, Voradian and several of our upstream provider partners are being blocked for incoming calls into China. Therefore, call completion to China is considered best effort only.
