Short answer: Use Outgoing → Global Settings to turn DID Fallback and Shared Route on/off for every outgoing call or campaign. Test a call after saving to confirm the behavior.
Setting | What it does | When to use | Notes |
DID Fallback | If the campaign’s primary DID can’t place calls (e.g., temporary carrier issue), the system automatically tries another your-account DID from the allowed pool. | You own multiple DIDs and want automatic resilience. | Caller ID may change to the fallback DID. Review compliance/branding. |
Shared Route | If your DID is unavailable, calls route via MyOperator shared DIDs to keep connectivity up. | You have limited DIDs or frequent peaks. | Recipient will see a shared number as CLI; ensure your team can handle return calls appropriately. |
