DTMF Tones

I hope this may help some peeps on here, it has worked for me,

we use a remote dialling code to divert our office landlines to mobiles, we have had awful trouble with the iphones in doing this with the number stored as a contact, We also have trouble dialling the number direct from the keypad it still comes up with error and says the number has not been recognised.

I have managed to sort out how to remedy this for us on this end and i will give an example below, the 'p' represents a pause

(numbers changed for security)

original phonebook contact stored, please notice the pauses 'p' only the first single pause

01223495684p*65*4530*01223456456*07555456456#

the new number now stored in the phonebook with the extra pauses 'p'

01223495684pp*65p*4530p*01223456456p*07555456456# as you can see we dial a landline number and then give a pause for the next tone to cut in, then we enter the overall divert code, after this we enter the pin code followed by the landline number to divert and finally the mobile number that will be taking the calls and finishing off with hash.

all our other phones except the iphone will dial this number and work correctly with one pause at the beginning, I have now tried thios with two pauses at the beginning and one pause between each section and it now works fine,

This has cured our problem using the io5 iphones 4s. we could not dial these numbers with the iphones for nothing, all other phones work fine. When you have a bluetooth headset connected the problem is even worse.

this has cured our problem and hope this helps you all also

iPhone 4S, iOS 5.0.1

Daryl,

Many thanks for this post....

I run a busy taxi company and as such all my calls to my lineline number (on O2) are routed to whichever driver is the duty drivers (mobile also on O2), using O2's Smart Divert system which means dialing a long string of numbers.

In the last week I decided to upgrade my phone from the Iphone 4 to the 4s.

On the iphone 4 Is was able to dail the number exactly as per your 1st example (

01223495684p*65*4530*01223456456*07555456456#) and it worked.

The 4s arrived and no joy.... it would not work.

Tried your method and it worked 1st time.

The annoying thing here is, I called O2 and after 2 hours on the phone in which time they called Apple it was decided that the phone was faulty.

They cocked up the delivery, by putting the wrong delivery address on the phone, costing me the loss of an airport jobs......

New phone arrived... and yes the same thing....

Called O2 again, a further 1 hour 20 mins, being told it was a fault !!!! finally put through to Apple Tech Support who told me they'd never heard of the problem and they thought that this must be an issue in the software.

I really hope that after reading this Apple and the operators take notice.Overall the lack of knowledge of each has cost me a few hundred pounds... and a lot of stress.

WELL DONE DARYL Brilliant post
