Regardless of which cellular carrier you use, you can mute your voice (microphone) during a call so that callers don't hear what you're doing. If you use a GSM cellular operator such as Telkomsel or XL, you can hold calls. This feature will mute both parties (both you and the other party) so you can make or receive other phone calls. You can also set up a conference call by accepting multiple calls.
