[asterisk-users] Problem with Aastra 480ci and qualify=yes

[James Lamanna]

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.
