The exact moment of the completion of the transmission of a communication, after which traffic data should be erased except for billing purposes, may depend on the type of electronic communications service that is provided. For instance for a voice telephony call the transmission will be completed as soon as either of the users terminates the connection. For electronic mail the transmission is completed as soon as the addressee collects the message, typically from the server of his service provider.
