I have tried adding my sangoma s500 phones to my free pbx. I have done the auto provision from sangoma and the EPM on freepbx, but everytime the phone comes on it has the login button, but when I press it is says “failed to load xml file!”. I am very new to this and need help!
I am not able to assign the mac. Anytime I go to map it as a custom extension it does not let me pick an extension it just says “custom extension”. I did follow the wiki step by step.
