    I am getting confused. I thought a DID was the phone number that comes in from your provider. For POTS, it would be:

    channel --> DID --> Destination


    The channel is mapped to the DID in Zap Channel DID's in FreePBX, then the DID is used to assign the channel to an Inbound Route in Elastix.

    Elastix Without Tears doesn't specifically define what it is.




    Thank You.

    but basically:

    DID = "Direct Inward Dial", i.e. the phone number being called, either explicitly in a DID trunk (T1/E1 SIP or IAX) where the individual calls identify the called number, or implicitly in a from-zaptel synthesis on DID less analog trunks, where you map all calls that arrive on that trunk which "implicitly" MUST be to that DID (with a few rare exceptions), to a synthetic DID number that you can route like any other call..

    don't confuse with:-



    CID ="Caller ID", the number that is calling your system, sometimes available, sometimes not,

    provide inbound routes to suit all of the above.
