Mitel handsets and Windows DHCP to update firmware?

[cajuntank]

I am wanting to upgrade some handset firmware to the latest rev of the SIP software code and need some assistance on what options to setup in windows DHCP to get the phones to boot. Also what do I need to do on the phones to swap them from using default MiNet over to SIP mode?

Have 5212, 5224, 5312, and 5324 model handsets.

Thanks.

The IP Phones are upgraded with the latest firmware automatticly by the normal DHCP settings to register the phones.
For SIP you need to go into the startup menu and change protocol to SIP. 52xx phones are only supporting SIP if they are dual mode phones. It will mention Duat on the back sticker.
