Caller id is asreceived

Hi,
i’ve asterisk 1.6.1 with freepbx 2.5.1.5 and a patton 4552.
The trunk have this peer config:
callerid=asreceived
context=from-zaptel
defaultip=192.168.XXX.XXX
dtmfmode=auto
host=dynamic
port=5060
qualify=yes
type=friend
username=XXX

When arrive a call show me asreceived and the call number.
But in some analog phone (connected to GXW4004) the lcd is small and show me only asreceived.
How can set the internal of analog phone to show me only the number and not the asreceived word?

Thank you.
