System and method for provision of a second line service to a telecommunications device using dialed sequence

A method for completing a communication setup initiated from an originating station and directed to a terminating destination, the method comprising:

• receiving a communication at a switch, the communication being sent from the originating station through an MTSO to the switch, and the communication comprising a dialed number;
• recognizing by the switch that the dialed number is a valid network telephone number;
• recognizing by the switch that the dialed number is a request for an SLS call;
• based at least in part on the dialed number, executing by the switch a programmed command to send a query message to an SLS platform that is communicatively coupled to the switch;
• holding by the switch the communication until the switch receives the reply to the query message from the SLS platform;
• and
• receiving at the switch a reply to the query message from the SLS platform, wherein the reply to the query message comprises:
• information for how to interpret the dialed number included with the communication for routing the communication to a correct terminating destination;
• and
• information indicating a CLID field to include with the communication, the CLID field comprising an SLS number of the originating station;
• and
• establishing a communication channel setup through the switch, based at least in part on the reply to the query message, wherein establishing the communication comprises connecting through the switch a voice channel circuit between the originating station and the terminating destination and routing the communication by populating by the switch the CLID field of data being transferred to the terminating destination with the SLS number of the originating station.

A method for routing a communication from an originating station, roaming on a second telecommunications network, to a terminating destination, wherein a first telecommunications network is the home network of the originating station, and the first telecommunications network and the second telecommunications network can be communicatively coupled and distinct networks, the method comprising:

• receiving a communication at a switch residing within the first telecommunications network, the communication being sent from the originating station that is roaming on the second telecommunications network, the communication comprising a trigger and a directory number;
• recognizing by the switch that the directory number is a 10 digit telephone number;
• recognizing by the switch that the trigger is configured to invoke an SLS call;
• transmitting from the switch, based at least in part on the trigger, a query message to an SLS platform residing within the first telecommunications network by:
• executing by the switch a programmed command to send the query message to the SLS platform;
• and
• holding by the switch the communication until the switch receives the reply to the query message from the SLS platform;
• receiving at the switch a reply to the query message from the SLS platform;
• and
• communicating to the second telecommunications network through the switch routing information for the communication including transmitting by the switch to the second telecommunications network an SLS number of the originating station for a CLID field of the terminating destination, based at least in part on the reply to the query message, wherein the reply to the query message comprises:
• routing information for the directory number included with the communication for routing the communication to a correct terminating destination;
• and
• information indicating the CLID field to include with the communication, the CLID field comprising the SLS number of the originating station.
