#### Routing Inbound Routes

**Step** **6**: For routing your inbound calls coming to your DID number, click on inbound routes and configure the DID with prefix 1. Toll-free numbers need to be configured without 1. Say your DID is 6014932412, then you will configure the DID with 16014932412 in the inbound routes.
