I've been looking around for an app that will tell me which number is being called. I have a business iPhone and personal. I want to know if it's personal or business line being called before I answer if I forward the personal to business iPhone. Allowing me to answer with the correct greeting. Thanks in advance for any info. Sorry if it is a repeat post. I'm not seeing anything else. I did see something for line2 app. But this seems to give you another number which I do not need.
