Asterisk 1.2 - sip_buddies restrictid does not work


I’m using Asterisk 1.2 with MySQL support. I use sip_buddies table for SIP clients definition. My problem is that I can not define CLIR. Sip.conf docs says that restrictid = yes hide caller identification. The problem is that definition of sip_buddies field named restrictid is char(1).
I tried to set restrictid = y, = 1 - no results. I changed definition of the filed to restrictid = char(3) and set it up to = yes. No results.

I have no idea what to do with it.
Have you?
