Abstract

The present invention informs a recipient of a holding non-voice call and allows the recipient to participate in real time text communication. A voice/text server is capable of communicating with a text device across a network or the Internet. The text device transmits the non-voice call to the voice/text server where the non-voice call is stored in a memory. The voice/text server generates a placeholder call and transmits the placeholder call to a voice telephone. The recipient receives the placeholder call by use of a voice telephone. A local text device generates a text link that is transmitted to the voice/text server. The voice/text server matches the text link to the holding text call. Text communication may then proceed between the users in any number of formats.
