We have 3300 running 8.0 SP3.  What DHCP options are required to use a external windows DHCP server? Are the ones I listed below all that is needed?

3 - VLAN default gateway (IPAddress)

66 - TFTP server. Use the IP addressof the 3300 (IP Address)

67 - TFTP BootFile. (ASCII String) “/sysro/E2T8260” Used by the E2T if present.

125 - Used by phones forbooting. (Combines options 128-133) (ASCII String)

Default ASCII string:

“id:ipphone.mitel.com;(required String)

sw_tftp=192.168.1.2;(IP address of 3300)

call_srv=192.168.1.2;(IP address of 3300)

vlan=1; (VLAN)

l2p=6;(Layer 2 network priority)

dscp=46” (DSCPpriority

You may need dns, but you will need the document for option 125 as it isn't an ascii string per se but encapsulated value
