Calling-Station-Id

Hi, I have Freeradius configured using a mysql backend. I want users to be able to connect only if their Calling-Station-Id is the same as the attribute I specify in the radcheck table in mysql. For example: |312|test@internet.quimefa.cu|Calling-Station-Id | == | "phonenumber" |298|test@internet.quimefa.cu|MD5-Password | := | password supposedly, I want to allow user test to only connect from this phonenumber, but when I really test the account I find that user test can connect from any phone number. So I really don't know what to do, I already tried to use different combinations of operators. Can anyone help me? in the radreply table I have this: |111|test@internet.quimefa.cu|Auth-Type|:=|Accept| thanks in advance.
