I am new to Elastix and am having trouble figuring out setting up DIDs. I have Elastix 1.5x with a dual port T1 card installed (but only 1 PRI coming in) with 8 channels active. All 8 channels are set up in a hunt group for the primary number. In addition, I have a total of 50 DIDs that have been assigned to me and a total of 75 extensions. I've setup all 75 extensions with an empty DID/CID, but would like to have at least 10 of them have their own DID assigned. I can add a DID and/or CID directly on the page for each extension, so that part seems clear. What I'm wanting to know is if want to pre-setup the remaining 40 DIDs, do I just enter them directly into the inbound routes page? Or is there a more straightforward way to accomplish this?
