Turning off Caller ID and Call Waiting

We need to block call waiting and caller ID from reaching a single SIP phone. The user must not be able to enable it at all. Any ideas on how to do this?

I think setting up callerid and incominglimit for this phone should do.

… in the user entry in sip.conf for the phone you want to restrict.
