Identification of calling devices dialing a universal number to access a telecommunications relay service center
First Claim
1. A telecommunications method that routes an originating call to an appropriate telecommunications relay service center within a local communications network interconnecting a plurality of service switching points, the originating call being in response to a calling party inputting a universal telephone number into a first communications device connected to a first service switching point, the first communications device having at least one identifier, the method comprising:
- ascertaining a toll free telephone number based upon the at least one identifier in response to the input universal telephone number, the toll free telephone number corresponding to the appropriate telecommunications relay service center, the at least one identifier comprises at least one of an automatic number identification (ANI) and a charge number (CN);
establishing a communications connection between the first communications device and the telecommunications relay service center based upon the ascertained toll free telephone number;
providing the at least one identifier to the telecommunications relay service center; and
