VoIP calls from a German phone number to another German phone number are often blocked by German telecom networks.
This is a regulatory and network-enforced restriction, not a technical issue, and not specific to Talk360.
What This Means for You
❌ German number → German number: Not supported in most cases
✅ German number → International number: Supported
✅ International number → German number: Supported
These rules apply across Germany and affect all internet-based calling services, not just Talk360.
Why Germany Blocks Local-to-Local VoIP Calls
German regulators (Bundesnetzagentur) require telecom carriers to strictly control how international and internet-based calls enter the German 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, German carriers must block calls that:
Are routed internationally, and
Display a German caller ID (+49), and
Are not confirmed as a genuine mobile roaming call
Because Talk360 is a VoIP service and not a local German telecom operator, calls that appear to be German-to-German are often blocked automatically by German networks.
What You Might Experience
When trying to call a German number from another German number using Talk360, you may notice:
Calls that fail immediately
Calls that never ring
Inconsistent call behaviour
This is expected under German 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 Germany
This is why Talk360 must follow these regulations strictly.
What You Can Do Instead
✅ Use Talk360 to make international calls
🌍 If you are calling Germany from abroad:
Use a non-German 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 German 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 Germany 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 German numbers fails, this is expected behavior, not a bug
