disabling in-call message notifications?

[Markham Asylum]

Hi guys, I just got a Galaxy 2 running Android 4.0. This is my first Samsung and first time using Android, so go easy on me please if this is a stupid question

When I get a text during a call, rather than just a quiet beep, it plays my full message alert. Is there any way I can disable this, because I cant hear the other person speak until the alert finishes.

Thanks

Mark

Settings > Call > Call alert > Alerts on call

Atleast on my Galaxy S2 there seems no way to change sound
