VoIP calls from a Swiss phone number to another Swiss phone number are often blocked by Swiss telecom networks.
This is a regulatory and network-enforced restriction, not a technical issue, and not specific to Talk360.
What This Means for You
❌ Swiss number → Swiss number: Not supported in most cases
✅ Swiss number → International number: Supported
✅ International number → Swiss number: Supported
These rules apply across Switzerland and affect all internet-based calling services, not just Talk360.
Why Switzerland Blocks Local-to-Local VoIP Calls
Swiss regulators require telecom carriers to strictly control how international and internet-based calls enter the Swiss phone network.
These rules exist to protect local telecom operators and enforce national telecom regulations.
To enforce this, Swiss carriers must block calls that:
Are routed internationally, and
Display a Swiss caller ID (+41), and
Are not confirmed as a genuine mobile roaming call
Because Talk360 is a VoIP service and not a local Swiss telecom operator, calls that appear to be Swiss-to-Swiss are often blocked automatically by Swiss networks.
What You Might Experience
When trying to call a Swiss number from another Swiss number using Talk360, you may notice:
Calls that fail immediately
Calls that never ring
Inconsistent call behaviour
This is expected under Swiss 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 Switzerland from abroad:
Use a non-Swiss 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 Swiss 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 Switzerland 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 Swiss numbers fails, this is expected behavior, not a bug
