EPM with Sangoma Phone not populating server field on phone

Greetings, I got my shiny new Sangoma phone in recently and I am testing it out now. I have gotten it to function with EPM via DHCP option 66 as well as with the Sangoma redirection server. However it will not register. From what I can see it appears as all settings have been sent to the phone minus the IP of the server to connect to for registration. What I mean is that if I look at the phone itself “SIP Server” is blank. I have this populated (correctly I believe) in the EPM globals as well as the Sangoma default template.
