- DHCP relay does not work on MX as the IP addresses on the site and relay servers are different.
- VOIP phone require dhcp option 156 for certain values, but I cannot get this to work as the IP Phones does not pickup this option. Please see below the option I have. If I can relay to another Windows Server, i know this option will work. But with MX running DHCP, i am not able to relay to another site.
