How to increase the delay before a call diverts to voicemail
July 10th, 2009You may find this of use, originally aimed at iPhone customers on the O2 network but should work on most networks and with all handsets (details taken from O2 website):
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).
Important Note:
In the example above 901 represents the number O2 customers dial to access their voicemail (irrespective of whether you are using an visual voicemail on an iPhone, 901 always dials into your voicemail system)
If your network uses a different (short) voicemail access number then simply substitute this and do not use 901
I have tested this on the O2 network and it works perfectly on the handsets I tried: iPhone, Nokia, Sony Ericsson. Each handset gives a different response (text) due to their operating system but usually it confirms that a voice call divert is active or similar (which is correct as your voicemail is simply a network function diverting unanswered calls to your voicemail account).
There’s no reason why it won’t work on all handsets and networks providing the network allows it’s subscribers to configure this setting.
Entering the above string of numbers isn’t the same as dialling a telephone number, although you do dial it like you would do a normal number. Your handset recognises it’s a network code and sends the instruction to your carrier and waits for a success/failure response which it then displays on your screen. You are not actually placing a voice call.
Obviously I cannot guarantee that this will work for you so all the usual disclaimers apply, and your mileage may vary.
Let me know how you get on.
