DID and CID?


I am confused on the difference between DID and CID. I know that DID stands for Direct in Dial and CID stands for Caller Id. I did google it on line but the examples that they put is kind of confusing… Can anyone please provide one good example??

Thank You

You call your mother from your cell phone or your PBX extension, she sees your “Caller*ID” as the number of your cellphone or your PBX extension.

Your PBX gets a call from your mother, the DID is the number you told here to call you and the Caller*ID is the number of her phone.
