First let’s talk about what composes words: due to a notable inefficiency to transmit complex sounds over what are often digital interfaces to the phone network, the speakers instead use DTMF signaling as a suport for their comunication. You can see here a table summarising the various tones available.

The reciver and sender parts of the packet contains information about who the message is intended for, as well as about who sends the message. Those are fully qualified phone numbers, including country prefixes, but no national escape. For example if sending a message to someone in britain, you would just use 44 as a national prefix.

The sequence number is a sequence of 3 tones interpreted as a decimal number that represents the number of messages previously sent by the sender to the recipient modulo 1000. This part allows to keep track of the grammar even if packets end up arriving out of order.
