In Call Sound Notifications

[Haifa83]

I searched for a solution to this and couldn't find anything so maybe someone knows how to do this.

I want to have sound notifications of things like voicemail, text, or appointment reminders...just not while I am on a call. I hate when I am talking to a friend and my phone starts chirping away (this is more of an issue when talking to clients and taking notes). Is there anyway to disable sound notifications while I am on a call??

Thanks in advance.
