FreePBX:  DIDs and Inbound routes
- 
 There's probably some n00b thing I'm missing, but if I create an inbound route which send a dialed DID to a particular extension, is there any reason to add the DID to the "Add Inbound DID" field for an extension?  
- 
 That is where you put the DID to be determined if it matches for the route to kick in. 
- 
 It is only an extra and it is not required. I have never used it. I only do it on the routes. 
- 
 Makes sense. I'll continue using the method of inbound routes.
