The Inbound Routes Module then tells FreePBX/Asterisk where to send these calls. Calls come into your system on trunks that are configured in the Trunks module.
Calls can be sent to a variety of destinations, including Extensions, Ring Groups, Queues, IVRs, Time Conditions, Feature Codes, DISAs, Conferences, etc., all of which are configured in their own modules.
Setting Up an Inbound Route to an Extension Manually
1. Go to Connectivity → Inbound Routes
2. Click the Add Inbound Route button.
3. Type in the new route a description.
4. Select the destination for this inbound route.
You must set this in order for your new inbound route to function properly.
5. Click Submit button
6. Click the Apply Config button.
You should now see your newly created route in the list at the upper right corner of the Inbound Routes module.
