I can see two lines and the top edge of a third and none of it means a thing, to me. Did you set the 3102 up according to the 3Cx info (leaving the * out of the caller Id field)? There are many, many, many options in the 3102, and the inbound call failure can be caused by the wrong info being in just one of them. Does the 3CX log show an incoming call attempt? Had the 3102 been used elsewhere, in other words did you provision it from a factory reset or just modify some of the settings after it was used in a previous installation?
