VOIP DHCP Option 43 Not Working | 8090DUFI Code L3

[corey_costello]

Hi,

I've got a VOIP phone, and option 43 converted over to hex.

I have verified that everything outside of the ICX is correct, because I can push the options to the phones from another vendor switch using the same hex string and a dhcp server locally on this vendors switch, as well as from another vendors firewall with DHCP, again using the same string.

I have ran pcaps and all the DHCP sequences look identitical, however the phone does not pull it's option from the hex string.

Thoughts?
