How do I turn off call connection and end tones on my Galaxy S6?

When making a call the S6 makes a connection tone and a disconnection tone at the end of the call.
You could turn this off on the S5 I cannot find where to turn it off on the S6.

Welcome to Android Central! Go to Settings>Call Settings>Call Alerts, and look for the Call Connection Tone option there.

I have the same problem with my Galaxy S6. I went into call settings and turned off the "Call connect tone" but I still hear three annoying beeps, that vary in tone depending on where I am calling from. Please send help. Thanx!
