Option 120 is SIP but when specifying it in Pfsense DHCP Server options i'm not sure what to set the type there!

These are the values which I would like to use in order to activate Pin authentication in our phones for Lync server.

Option 120:
00086C796E636672656E0964656D6F7617303636F6D00

Vendor Class Identifier: MS-UC-Client

Option 43 (for vendor=MS-UC-Client):
        sub-option 1 <uc identifier="">: 4D53232D436C69656E74
        sub-option 2 <url scheme="">: 68747073
        sub-option 3 <web server="" fqdn="">: 6C796E636672656E2E732E636F6D
        sub-option 4 <port>: 343433
        sub-option 5 <relative path="" for="" cert="" prov="">: 2F4365727450726F762F4365727450726F766973696F6963652E737663

Any help is appreciated.
Thanks</relative></port></web></url></uc>
