ABSTRACT:
A method, system, and medium are provided for routing a call through telecommunications relay services while maintaining desired call information. The present invention includes routing calls through the telecommunications relay services system using a variety of signaling protocols while maintaining call information. A method of integrating line information into a telephone signal is provided. The method includes receiving line information in a packet header and parsing the header to extract the line record information. The parsed information is converted into a set-up message in Integrated Services Digital Network protocol. The method also determines if a specific telephony carrier is identified in the parsed header. If a specific telephone carrier is identified, the signal is directed to the identified carrier along with the set-up message.
