Systems and methods for information exchange and synchronization using DTMF over telephone communication channels

A first device, comprising:

• a memory;
• and
• a processor configured to:
• convert information received during an active communication session between the first device and a second device into a three digit binary coded decimal (BCD) format,
• convert the information from the three digit BCD format to a dual tone multiple frequency (DTMF) signal, and
• transmit the DTMF signal from the first device to the second device over a network during the active communication session.

A first device, comprising:

• a memory;
• and
• a processor configured to:
• convert a packet having an ASCII format into a code having a three digit binary coded decimal (BCD) format, wherein each set of three digits in the code represents a character in the packet, wherein information in the packet is received during an active communication session between the first device and a second device,
• convert the code from the three digit BCD format to a dual tone multiple frequency (DTMF) signal, and
• transmit the DTMF signal from the first device to second device over a network during the active communication session.
