When a call comes in, you may not want to answer it, or you may need to stop iPhone from ringing or vibrating. You can silence or decline an incoming call.

When you silence a call, you still have a chance to answer it, until the call goes to voicemail. When you decline a call, the call is silenced and sent directly to voicemail.

It is possible to configure the call go directly to voicemail?
(Now 1.1.1 to do this, it gives busy tone)
To some it working properly?


**I apologize for my bad English

Perhaps you can set call forwarding (when available) straight to your voice mail number? Just a thought....

If possible ... The problem is that I do not receive any calls, all go straight to voicemail :-)
I always had the warning popup "Call forwarding active" but I quite visually.

I've been thinking about workarounds. One would be to use forwarding *#67#
This tells me:
Voice Call Forwarding
When Busy
Disable

You can activate using commands?

Solution!! :) ..

Busy Call Forwarding: Dial *67* plus the 10-digit number to which your calls should be forwarded and #. Press Send.

Call Forwarding No Reply: Dial *61* plus the 10-digit number to which your calls should be forwarded and #. Press Send.

Call Forwarding Not Reachable: Dial *62* plus the 10-digit number to which your calls should be forwarded and #. Press Send.

Do this:
Forward if Out of Reach
- Activate *62*[PHONE NUMBER]#
- Cancel & De-register ##62#
- Cancel & Retain #62#
- Status *#62#
- Re-establish *62#
