I followed the provisioning instructions on the 3CX website where it says the following: "*In case you are using the snom M300, please change from the “Phone Provisioning Tab” the model from Snom 300 to Snom M300!" The problem is that there is no Snom M300 option in the "Phone Provisioning Tab". When I complete the provisioning selecting the default "Snow 300" the base station does not provision i.e. the extension status remains as "Not Registered". Can someone please help? Any ideas?
