Boot Server (TFTP) is usually option 066 in dhcp, in many cases it requires a hostname, not an IP address, so you have to make sure that the device is DNS aware and that the hostname you specify in option 066 is in the same DNS that phone uses. If option 066 does not work try exploring option 150 on your DHCP server.
 
Not sure if this applies to the Aastra phone since I do not have one to test, but let us know.

Subject: [Asterisk-Users] DHCP Attribute for TFTP server for Aastra 480i?

I have this Aastra 480i phone, and you can set the TFTP server IP address manually in the phone, but there should be a way to have it find the TFTP server information via DHCP. Does anyone know if this is possible, and if so, what is the attribute I have to set on my DHCP server? Thanks!
