What is the difference between Application-to-Person (A2P) and Person-to-Person (P2P) traffic?
A2P refers to application-to-person messages (an app, alert, 2FA, etc.) and are generally related to a transaction. The assumption is that an A2P SMS was generated by a software application.
P2P refers to person-to-person messages, where a person sends a message to another person. The nature of this traffic would resemble a conversation or dialogue, rather than being related to a transaction.
