VoIP calls from a Brazilian phone number to another Brazilian phone number are often blocked by Brazilian telecom networks.
This is a regulatory and network-enforced restriction, not a technical issue, and not specific to Talk360.
What This Means for You
❌ Brazilian number → Brazilian number: Not supported in most cases
✅ Brazilian number → International number: Supported
✅ International number → Brazilian number: Supported
These rules apply across Brazil and affect all internet-based calling services, not just Talk360.
Why Brazil Blocks Local-to-Local VoIP Calls
Brazilian regulators (ANATEL) require telecom carriers to strictly control how international and internet-based calls enter the Brazilian 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, Brazilian carriers must block calls that:
Are routed internationally, and
Display a Brazilian caller ID (+55), and
Are not confirmed as a genuine mobile roaming call
Because Talk360 is a VoIP service and not a local Brazilian telecom operator, calls that appear to be Brazilian-to-Brazilian are often blocked automatically by Brazilian networks.
What You Might Experience
When trying to call a Brazilian number from another Brazilian number using Talk360, you may notice:
Calls that fail immediately
Calls that never ring
Inconsistent call behaviour
This is expected under Brazilian 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 Brazil
This is why Talk360 must follow these regulations strictly.
What You Can Do Instead
✅ Use Talk360 to make international calls
🌍 If you are calling Brazil from abroad:
Use a non-Brazilian 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 Brazilian 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 Brazil 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 Brazilian numbers fails, this is expected behavior, not a bug
