asterisk users - Feb 2007 - IAX Realtime - show peers works?

hi all, I'm trying to set up some iax2 trunks in Realtime architecture 
with the same backend.
All work better (make call, receive etc etc) but when I do "iax2 show 
peers" some asterisk don't show anything and other show the iax2 peers 
but with status "unknow".

Name/Username    Host                 Mask             Port 
Status

ctm1/trixbox     10.0.0.131      (S)  255.255.255.255  4569 
UNKNOWN

I have set in iax.conf rtcachefriends=yes but the status not change.
There are anyone with this situation  that iax2 show peers work?

One of my mysql records:

INSERT INTO `iax_buddies` (`name`, `username`, `type`, `secret`, 
`md5secret`, `dbsecret`, `notransfer`, `inkeys`, `outkey`, `auth`, 
`accountcode`, `amaflags`, `callerid`, `context`, `defaultip`, `host`, 
`language`, `mailbox`, `deny`, `permit`, `qualify`, `disallow`, `allow`, 
`ipaddr`, `port`, `regseconds`) VALUES
('ctm2', 'trixbox', 'friend', 'XXXXX', NULL,
NULL, NULL, NULL, NULL,
NULL, NULL, NULL, NULL, 'fromiax', NULL, '10.0.0.254', NULL,
NULL, NULL,
NULL, 'yes', 'all', 'alaw', NULL, 4569, 0);
