Dealing non-windows environment has always been exciting for a windows professional. A non-windows DHCP server can be configured with hex value to support Lync phone login. Usually this is what you configure in Windows DHCP server.
Which you can convert to hex using any online string to hex converter. However it may not be sufficient. During an engagement I used several string to hex converters, but of no use. Finally I used the tool which I should have used at first go; DHCPUtil.exe. :)
Located DHCPUtil.exe on Lync server (%ProgramFiles%\Common Files\Microsoft Lync Server 2013) command prompt. Ran following command.
DHCPUtil.exe -SipServer lyncpool.contoso.com -WebServer lyncweb.contoso.com >Hex.txt
It created a file Hex.txt under %ProgramFiles%\Common Files\Microsoft Lync Server 2013. This file has corresponding hex values for DHCP scope options. We could login in Lync phone clients (hard reboot is required) successfully after configuring the DHCP server with HEX values.
