asterisk users - Aug 2008 - Problem with Aastra 480ci and qualify=yes

Hi,
We have a few Aastra 480ci phones and we've noticed that in order to
get the phone to receive a call, qualify must be = no.
Apparently the Aastras do not respond to the qualify message (or
respond in a way Asterisk doesn't understand) and Asterisk thinks the
phone is unreachable.
However, this now prevents MWI from working properly on the phones.

Does anyone know how to get MWI working without qualify? Or how to get
qualify working again with the Aastras?

Thanks.

We have a number of 480i and one 480ct all setup with "qualify=yes" 
(Asterisk 1.2.24)
Our inbound call centre seems to be pretty busy and my own MWI lights up 
far too often. Never had a problem with either.

Which version of firmware?
Which version of Asterisk?
What's in your sip.conf?
What error messages show on the console?
Anything relevant in the logs?

regards,

Drew
