Abstract: The present invention enables the user of a VOIP device to place simultaneous calls to multiple users and invite them to a conference using a pre-defined code. In a preferred embodiment, the user can customize a dynamic two digit code and associate a list of phone numbers with it. The present invention does away with the need to use a ‘*’ or a ‘#’ as a prefix when initialing a control code call. Therefore, if the user wants the phone to do something, i.e., call forwarding, hold, block number etc, the user no longer has to press ‘*98’. The user can simply input 98 and the system will recognize it as a control code call command. The system accomplishes this task by determining a pre-determined amount of time that has passed after the user entered the last phone digit.
