# Why Aren't Calls Following the Campaign IVR Treatment?

> A promo number customized at the number level can follow its own IVR call treatment instead of the main campaign's — check the Manage Promo Numbers page to confirm.

If calls aren't routing through a Lookup Table or static Marketing Data as expected, check whether the number is customized at the promo number level. Customized numbers can follow a separate IVR call treatment from the main campaign.

Another way to check for customization is to look at the destination number on the Manage Promo Numbers page — if it doesn't match the campaign name, the number is likely customized.

**Applies to:** Campaigns, IVR call treatment
