VoIP calls from a Chinese phone number to another Chinese phone number are often blocked or severely disrupted by Chinese telecom networks.
This is a regulatory and government-enforced restriction, not a technical issue, and not specific to Talk360.
What This Means for You
❌ Chinese number → Chinese number: Not supported in most cases
⚠️ Chinese number → International number: Often unreliable
⚠️ International number → Chinese number: Sometimes possible, but unstable
These rules apply across China and affect all internet-based calling services, not just Talk360.
Why China Blocks Local-to-Local VoIP Calls
Chinese regulators strictly control all internet-based communication, including VoIP calls. These controls are among the most stringent in the world.
These rules exist to prevent:
Caller ID spoofing (calls pretending to be local)
Fraud and scam calls
Abuse of international routing
To enforce this, Chinese carriers block or filter calls that:
Are routed internationally, and
Display a Chinese caller ID (+86), and
Are not confirmed as a genuine mobile roaming call
Because Talk360 is a VoIP service and not a local Chinese telecom operator, calls that appear to be Chinese-to-Chinese are blocked or disrupted by Chinese networks.
What You Might Experience
When trying to call a Chinese number from another Chinese number using Talk360, you may notice:
Calls that fail immediately
Calls that never ring
Inconsistent call behaviour — working sometimes, failing other times
One-way audio or calls that drop suddenly
This is expected under Chinese telecom rules and does not mean:
Your account is blocked
Your balance is missing
The app is broken
Failed calls do not deduct credit.
Can Talk360 Request an Exception?
No.
There is:
No approval or exception process
No way for individual apps to request special permission
These rules apply equally to all VoIP providers.
Providers that do not comply may face:
Heavy fines
Network blocking
Loss of the right to operate in China
This is why Talk360 must follow these regulations strictly.
Important to Know
These limitations are enforced by Chinese telecom networks and government regulation
VPNs or routing tricks will not solve this
Call behavior may change without notice based on carrier rules
Repeated very short calls can trigger spam or fraud detection — wait before retrying
These restrictions are outside Talk360's control
Key Takeaway
Local-to-local VoIP calls in China are blocked by government regulation
This is a legal restriction, not a technical problem
The same rules apply to all VoIP services
International calling may be possible but is often unstable
If a call between Chinese numbers fails, this is expected behavior, not a bug
