Configuring call treatments and call routing
Since CLID numbers are most commonly used with international dialing plans
to check against calling party information, they are allowed to contain flexible
digit notations (wildcard and placeholder).
The following special rules apply to the formatting of CLID numbers.
You can
use only one wildcard in any one CLID digit string (for example, the digit
!
string @345@ is not valid)
use a wildcard only at either the beginning or end of a CLID digit string
!
use a wildcard only in the CLID digit string
!
use placeholders only in the CLID intrinsic
!
use both wildcards and placeholders in a CLID digit string, with the above
!
rules still applying to wildcard and placeholder placement
