@Kevin Elliott Sorry I should have clarified that. No I don't mean a Voip call I mean a regular call. For example, identifying information about the caller might be in the P-Asserted-Identitiy field, or an image might be specified in the Call-Info header (with purpose=icon). So I was wondering, for example suppose a call arrived and P-Asserted-Identity was empty but Call-Info contained an icon, and LCID returned a name but no icon, then would the OS combine the icon from Call-Info with the name from LCID to display a name and an icon?

Are you looking for a solution in Swift or Objective-C to this sharpness?

@eskimo, in that video you reference, he says there are three ways to avoid the prompt being displayed and lists what they are but then only goes on to talk about the 3rd of the three. I don't understand what is meant by the first two ways: Edit Options, and Keyboard Shortcuts. What is meant by these, and how do they avoid the prompt being displayed?
