This incident is now set to Resolved.
For impacted customers, if you have a local entity and local representative in China, it is recommended to buy a China number from Vonage to make outbound calls to China.
Due to heavy filtering by China operators, our international route to China is best effort only. Calls may get blocked without prior warning.
