Responding to a telephone call made by a calling party includes receiving a first telephone call and identifying an account associated with the telephone number to which the first calling party directed the first telephone call. Configuration data related to the account is accessed. A first identity associated with the account is identified based on the configuration data accessed. A first electronic communication is sent to a computer of a first called party associated with the first identity. The first called party may respond to the first electronic communication by dynamically and manually inputting a call redirection telephone number, sending an e-mail, or sending an instant message. If a call redirection telephone number is inputted, the first telephone call may be redirected to the call redirection telephone number.
