    I have a Lumia 620. Whenever I need to send dtmf tones (built in from contacts, not manually touching the dial-pad), it sends the tone very rapidly so the receiving systems do not recognize the tones. I have no problem with putting pauses or hard wait in the contacts, but problem with the tones sent one after the other rapidly. For example if I need to send 4 tones, the phone does it very quickly. Is there a program that I can use to customize the delay between tones? Or a setting that I can tweak? Putting pauses between the tones is not an option because a pause is 2 second delay, which might mess with the receiving system.

    Thanks.
