Inbound Rules are how the phone system dictates where a call will be directed for a set phone number (DID). These phone numbers must be setup when the SIP trunk is added to the system. 

To ensure a smooth process of adding inbound rules, we recommend that the following destinations have been setup: 

• SIP Trunks
• Extensions
• IVR/Auto-Attendant
• Call Queues
• Ring Groups

Setting up an Inbound Rule

1. Log into the bvoip phone system.
2. Click on the Call Flow drop-down menu.
   
3.  Go to the Inbound Rules subsection.
4. Click on the Add DID button to add each DID number. The page will refresh.
5. Scroll to the Trunk Details section.
   
6. In the Name field, list a name to differentiate it from other DIDs. 
7. In the DID/DDI field, select the desired DID from the drop-down. 
8. Go to the Route Calls To section.
   
    
9. Select the Destination For Calls During Office Hours by clicking on the two drop-downs beneath it. 
10. Select the Destination For Calls Outside Office Hours by clicking on the two drop-downs beneath it.
11. Select the Setup Specific Office Hours for this Rule if the phone number tied to this inbound rule will have different office hours that the other inbound rules. If this option is selected, the section to have the hours configured will appear.
12. Select the Redirect calls to HOL IVR when it's a system holiday option if the inbound rule needs to respect the global holidays set in the system. For a guide on this, please see our article on Setting Holiday Hours Functionality. 
13. Click on the Save button. Repeat the above steps for each inbound rule.
