Greetings! Can I set a 3rd party SIP / VoIP Phone to answer an iPhone call on my Mac? I want to replace apples 'Accept / Decline' pop up that appears on a Mac when a call comes into my iPhone with a 3rd party phone. Is this even possible? I'm not wanting to do special things to my computer, the 3rd party phone needs to have it in the install file (I own it and will be distributing it). Any help would be highly appreciated. Thank you! This image is what I'm talking about replacing with a 3rd party soft-phone.
