What this page is for
This guide explains the difference between the main forwarding-number types used in Sendblue call routing.
The core distinction
| Type | What it usually means |
|---|---|
| Default forwarding number | The fallback destination used when no more specific rule overrides it. |
| User-specific forwarding number | A forwarding destination tied to a specific user or owner context instead of the global/default path. |
How to choose the right type
Use the default forwarding number when one general destination should handle most calls.
Use user-specific forwarding when calls should follow the assigned owner or specific internal user.
Common mistakes
Forgetting that a user-specific rule may override the default.
Assuming calls should hit the default when a user-level rule is still active.
