It's configured on your upstream telco switch. There's probably some number
translation going on there.

CLI (Calling Line Identifier) is the Calling-Station-Id - the phone number
calling *from* - and is 7 digits as you see.

CSID (Called Station ID) is the Called-Station-Id - the phone number calling
*to*. If you want to see all 7 digits of that, you'll have to ask your Telco
to send you 7 digits of CSID.

Usually, having a shortened CSID is not a problem - as long as (a) the Telco
doesn't change it under your nose without telling you, and (b) you don't
need more than 10,000 phone numbers or more than one prefix. But I agree
it's nice to see the full number.
