Abstract

A system uses conventional text messaging capabilities of cellular telephone systems to embed one or more call-back telephone numbers. A start delimiter is used to separate a text data portion corresponding to the call-back telephone number from the text message. A termination delimiter may be used to indicate the end of the text data portion corresponding to the call-back telephone number. Multiple text data portions, corresponding to multiple call-back telephone numbers, may be inserted using multiple start delimiters and termination delimiters. A text parser in the cellular telephone searches the text message for the start delimiter and extracts the text data portion corresponding to the call-back telephone number. The cellular telephone user selects a desired call-back telephone number, which may be placed in a dialing queue for simplified communications between the cellular telephone and a destination corresponding to the selected call-back telephone number.
