iPhone: Increase Time before Call Goes to Voicemail
Contributed by David Kirk 
Tagged: Apple iPhone My iPhone always seems to jump to voicemail before I answer it. I need to increase the call forward delay. By increasing the delay before the call is transferred to voicemail, I have a better chance of grabbing it. As expected, the caller will hear an increased number of rings before being transferred.
This requires a little friendly hacking of your iphone. Call your iphone now from a different line to judge how long it takes to hit voicemail.
1. From the keypad dial the following: *#61#
2. Press the Call button
3. Write down your voicemail number. It’s the number after “Forwards to”
4. From the keypad dial the following: *61*1VOICEMAILNUMBER*11*30# inserting your voicemail number where VOICEMAILNUMBER is. It should be 11 numbers.
(For example, if your voicemail number is 16787641111 then your command would be: *61*16787641111*11*30#)
30 is the length of time in the command above. 20 is the default. 30 is the max.
5. Press the Call button to send your command to the server
6. You should see the following:
Setting Activation Succeeded
Voice Call Forwarding
When Unanswered
7. Congrats. You are set! Call your iphone again to see that it now takes longer to hit voicemail.
If you bugger you phone, don’t blame me. Do this at your own risk. If you want to be super safe, you can call AT&T and they will do this for you as well.

Very splendid, worked great on my 3G phone. Now maybe I’ll have time to get to the phone when I’m at home.

you have an extra “1″ in line 4 or your otherwise very helpful instruction on changing the ring time. It is after the second *.

For those in the UK on O2, the information is similiar, and available on their website…

Their guidance…
Can I increase the length of time my iPhone rings before diverting to voicemail?
Yes, just like any other handset you can change the length of time the iPhone rings before diverting to voicemail by entering **61*901*11*NN# SEND (NN is the number of seconds in increments of 5 and a maximum of 30 seconds).

Please note on command nr 4 you do not need the “1″ in front of the VOICEMAIL nr.

This didn’t work at first but then I added the hatch key after the first star and the 61 and it worked – so I’m very happy as this was driving me nuts and everyone else who was trying to call me!!

Thanks so much! This works great for Google Voice too. I like to get all my voicemails via Google Voice so they’re transcribed and sent as texts. This hack makes sure missed calls go to Google Voicemail before the iPhone voicemail picks up.
