Hi there, We've 3cx v12 system running and I want to buy Htek uc804 IP Phone which is supported on 3cx system. Phone provisioning for Uc804 is clearly explained in the following article. http://www.3cx.com/sip-phones/htek-uc804-uc840-uc860/ However I can not see the model for Htek UC804 in the extensions-> phone provisioning tab -> Model (dropdown menu to select the model) Should I buy this phone and provision without any problems? What should I do when I should select the model? The model isnt in the list!!!!
