VoIP calls from a US phone number to another US phone number are often blocked by US telecom networks.
This is a regulatory and network-enforced restriction, not a technical issue, and not specific to Talk360.
What This Means for You
❌ US number → US number: Not supported in most cases
✅ US number → International number: Supported
✅ International number → US number: Supported
These rules apply across the United States and affect all internet-based calling services, not just Talk360.
Why the US Blocks Local-to-Local VoIP Calls
US regulators and carriers strictly control how international and internet-based calls enter the US phone network.
These rules exist to prevent caller ID spoofing, fraud, and scam calls.
To enforce this, US carriers must block calls that:
Are routed internationally, and
Display a US caller ID (+1), and
Are not confirmed as a genuine mobile roaming call
Because Talk360 is a VoIP service and not a local US telecom operator, calls that appear to be US-to-US are often blocked automatically by US networks.
What You Might Experience
When trying to call a US number from another US number using Talk360, you may notice:
Calls that fail immediately
Calls that never ring
Inconsistent call behaviour
This is expected under US 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.
This is why Talk360 must follow these regulations strictly.
What You Can Do Instead
✅ Use Talk360 to make international calls
🌍 If you are calling the US from abroad:
Use a non-US 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 US 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 the US 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 US numbers fails, this is expected behavior, not a bug
