Telecommunications system

A telecommunications system, comprising:

• a primary mobile device with a primary phone number, the primary mobile device configured to permit call forwarding;
• a primary carrier system, the primary mobile device in communication with the primary carrier system;
• a secondary mobile device with a secondary phone number, the second mobile device operating on the third-generation (3G) cellular technology or later generation cellular technology, the secondary mobile device configured to store configuration data and telemetry data;
• a secondary carrier system, the secondary mobile device in communication with the secondary carrier system;
• a call-handling switch in communication with each of the primary carrier system and the secondary carrier system;
• and
• a cloud server node in communication with the secondary mobile device and the call-handling switch, the cloud server node having at least one database, the cloud server node configured to directly synchronize with the secondary mobile device without an intervening proxy system, the cloud server node configured to receive and store the secondary phone number, the configuration data, and the telemetry data of the secondary mobile device in the database, and to verify, log, and control all communications from the secondary mobile device through the call-handling switch, and the cloud server node also configured to receive and store the primary phone number of the primary mobile device in the database, the configuration data including an association of the primary phone number of the primary mobile device with the secondary phone number of the secondary mobile device,
• wherein, during an outbound call from the secondary mobile device, an outbound audio signal is generated at the secondary mobile device and communicated via the secondary carrier system to the call-handling switch, the outbound audio signal including a caller-id header with an outbound dual-tone multi-frequency (DTMF) signal encoding a caller-id associated with the second phone number of the secondary mobile device, and the call-handling switch communicates the outbound audio signal to the cloud server node, and the cloud server node converts the outbound DTMF signal to a data signal and correlates the secondary phone number given by the data signal converted from the caller-id header with the primary phone number, and the cloud server node communicates the primary phone number to the call-handling switch, and the call-handling switch delivers the outbound call to an external device, whereby the external device is given a caller-id set to the primary phone number instead of the secondary phone number, and
• wherein, during an inbound call from the external device with an external phone number, an inbound audio signal is generated at the external device and communicated by the primary carrier system to the call-handling switch via a call forwarding setting of the primary mobile device, the inbound audio signal including a caller-id data signal associated with the external phone number of the external device, and the call-handling switch communicates the inbound audio signal to the cloud server node, and the cloud server node converts the caller-id data signal to an inbound DTMF signal, and the cloud server node communicated the inbound DTMF signal to the call-handling switch, and the call-handling switch delivers the inbound audio signal with the inbound DTMF signal to the secondary mobile device, whereby the second mobile device is given the external phone number associated with the external device.

A method for using a telecommunications system, the telecommunications system including a primary mobile device, a primary carrier system, a secondary mobile device, a secondary carrier system, a call-handling switch, and a cloud server node, the primary mobile device having a primary phone number, the primary mobile device configured to permit call forwarding, the primary mobile device in communication with the primary carrier system, the secondary mobile device having a secondary phone number, the secondary mobile device operating on a second-generation (2G) cellular technology, the secondary mobile device configured to store configuration data and telemetry data, the secondary mobile device in communication with the secondary carrier system, the call-handling switch in communication with each of the primary carrier system and the secondary carrier system, and the cloud server node in communication with the call-handling switch, the cloud server node having at least one database, the cloud server node configured to receive and store the secondary phone number, the configuration data, and the telemetry data of the secondary mobile in the database and to verify, log, and control all communications from the secondary mobile device through the call-handling switch, and the cloud server node also configured to receive and store the primary phone number of the primary mobile device in the database, the configuration data including an association of the primary phone number of the primary mobile device with the secondary phone number of the secondary mobile device, the method comprising the steps of:

• at least one of
• a) during an outbound call from the secondary mobile device,
• i) generating an outbound audio signal at the secondary mobile device;
• ii) communicating the outbound audio signal via the secondary carrier system to the call-handling switch, the outbound audio signal including a caller-id header with an outbound dual-tone multi-frequency (DTMF) signal encoding a caller-id associated with the second phone number of the secondary mobile device;
• iii) communicating, by the call-handling switch, the outbound audio signal to the cloud server node;
• iv) converting, by the cloud server node, the outbound DTMF signal to a data signal and correlating the secondary phone number given by the data signal converted from the caller-id header with the primary phone number;
• v) communicating, by the cloud server node, the primary phone number to the call-handling switch;
• and
• vi) delivering, by the call-handling switch, the outbound call to an external device, whereby the external device is given a caller-id set to the primary phone number instead of the secondary phone number,
• and
• b) during an inbound call from the external device with an external phone number;
• i) generating an inbound audio signal at the external device;
• ii) communicating, by the primary carrier system to the call-handling switch via a call forwarding setting of the primary mobile device, the inbound audio signal including a caller-id data signal associated with the external phone number of the external device;
• iii) communicating, by the call-handling switch, the inbound audio signal to the cloud server node;
• iv) converting, by the cloud server node, the caller-id data signal to an inbound DTMF signal;
• v) communicating, by the cloud server node, the inbound DTMF signal to the call-handling switch;
• and
• vi) delivering, by the call-handling switch, the inbound audio signal with the inbound DTMF signal to the secondary mobile device, whereby the second mobile device is given the external phone number associated with the external device.
