Method and system for sending messages over telecommunication networks

A computer readable medium comprising instructions that when executed by a processor executes a process for sending messages between telephone terminals, the process comprising:

• coding a message in an emitting terminal as a specific duration time of an unanswered call;
• making a call with that specific duration time;
• and
• decoding the message corresponding to the duration of the received call in a receiving terminal;
• wherein
• the message to be sent is one selected from a plurality of available messages;
• and
• the coding message, a time of the call, and a decoding time of the call are performed by consulting a coding table relating each message of the plurality of available messages with a specific time.

A system for sending messages between telephony terminals, comprising at least one telephony terminal:

• a memory suitable for storing at least one coding table relating each message of a plurality of messages with a specific duration of an unanswered call, and
• a computer processor configured for
• coding a message in an emitting terminal as a specific duration time of an unanswered call;
• making a call with that specific duration time;
• and
• decoding the message corresponding to the duration of the received call in a receiving terminal;
• wherein
• the message to be sent is one selected from a plurality of available messages;
• and
• the coding message, a time of the call, and a decoding time of the call are performed by consulting a coding table relating each message of the plurality of available messages with a specific time.
