VoIP calls from a Taiwanese phone number to another Taiwanese phone number are often blocked by Taiwanese telecom networks.
This is a regulatory and network-enforced restriction, not a technical issue, and not specific to Talk360.
What This Means for You
❌ Taiwanese number → Taiwanese number: Not supported in most cases
✅ Taiwanese number → International number: Supported
✅ International number → Taiwanese number: Supported
These rules apply across Taiwan and affect all internet-based calling services, not just Talk360.
Why Taiwan Blocks Local-to-Local VoIP Calls
Taiwanese regulators (NCC) require telecom carriers to strictly control how international and internet-based calls enter the Taiwanese phone network.
These rules exist to prevent:
Caller ID spoofing (calls pretending to be local)
Fraud and scam calls
Abuse of international routing
To enforce this, Taiwanese carriers must block calls that:
Are routed internationally, and
Display a Taiwanese caller ID (+886), and
Are not confirmed as a genuine mobile roaming call
Because Talk360 is a VoIP service and not a local Taiwanese telecom operator, calls that appear to be Taiwanese-to-Taiwanese are often blocked automatically by Taiwanese networks.
What You Might Experience
When trying to call a Taiwanese number from another Taiwanese number using Talk360, you may notice:
Calls that fail immediately
Calls that never ring
Inconsistent call behaviour
This is expected under Taiwanese telecom rules and does not mean:
Your account is blocked
Your balance is missing
The app is broken
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 Taiwan
This is why Talk360 must follow these regulations strictly.
What You Can Do Instead
✅ Use Talk360 to make international calls
🌍 If you are calling Taiwan from abroad:
Use a non-Taiwanese caller ID
This is the most reliable setup
⚠️ Attempting to bypass these restrictions is not supported and may be illegal.
Important to Know
These limitations are enforced by Taiwanese telecom networks
VPNs or routing tricks will not solve this
Call behavior may change without notice based on carrier rules
These restrictions are outside Talk360's control
Key Takeaway
Local-to-local VoIP calls in Taiwan are often blocked by regulation
This is a legal restriction, not a technical problem
The same rules apply to all VoIP services
International calling is supported
If a call between Taiwanese numbers fails, this is expected behavior, not a bug
