<p>Embodiments of the present invention provide a method, system and device for authenticating an IP phone and negotiating a voice domain, so as to implement a dynamic security authentication and negotiation. The method includes: receiving an authentication request packet sent by an internet-based phone IP Phone; encapsulating an user name and password of the IP Phone in a remote authentication dial in user service RADIUS request packet, and sending the RADIUS packet encapsulating the user name and password of the IP Phone to a RADIUS server; and if a result of the authentication performed by the RADIUS server on the IP Phone is that the authentication succeeds, sending a voice domain virtual local area network Voice VLAN value to the IP Phone through an extensible authentication protocol EAP extension packet. In the present invention, dynamic security authentication and negotiation functions between a client and a server, and rapid deployment of an internal network of an enterprise may be implemented.</p> |
