Third party call control utilizing a voice user interface

摘要

A method is described herein which enables a person to use their mobile phone to establish a voice connection with a central server, then send call control information in-band in the voice channel (via a voice user interface (VUI), digital tone multi-frequency (DTMF) or Multi-Frequency (MF) signaling) to setup a call between a convenient phone (e.g., land-line phone or mobile phone which has a better tariff structure) and one or more destination phone(s). Once the call is setup, the mobile phone can be hung-up to save on mobile connection costs and then a person can use the convenient phone to talk to a person using the destination phone.
