Hi, without searching the community by myself, but I bet, your question has been asked already a lot in the forum. So use the internet or forum search.
Note: You first have to check, if your phone is an enterprise phone (only possible to register on CUCM) or an MPP phone (possible to register to 3rd party PBX).
