The session authentication method comprises: detecting whether an authentication mode is started up or not; automatically acquiring verification request information stored locally; transmitting the verification request information to a calling party via the DTMF, and receiving verification key information looked up by the calling party according to the verification request information and fed back via the DTMF; performing verification authentication on the key information and a key stored locally; and when the verification authentication is passed, accessing an inbound session. By means of the method of setting the authentication mode and by automatically transmitting verification via a DTMF, the method is convenient for a user to operate and use. |
