Method, System and Device for Authenticating IP Phone and Negotiating Voice Domain

摘要

A method for authenticating an IP phone and negotiating a voice domain includes receiving an authentication request packet sent by an IP Phone, encapsulating a user name and password of the IP Phone in a RADIUS request packet, and sending the RADIUS packet encapsulating the user name and password of the IP Phone to a RADIUS server. If a result of the authentication performed by the RADIUS server on the IP Phone is that the authentication succeeds, sending a Voice VLAN value to the IP Phone through an extensible authentication protocol EAP extension packet. In the present application, 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.

1. A method for authenticating an internet protocol (IP) Phone and negotiating a voice domain, comprising:
receiving an authentication request packet sent by the IP Phone, wherein the authentication request packet carries a user name of the IP Phone and a password of the IP Phone; encapsulating the user name of the IP Phone and the password of the IP Phone in a remote authentication dial in user service (RADIUS) request packet, and sending the RADIUS request packet encapsulating the user name of the IP Phone and the password of the IP Phone to a RADIUS server; and when 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.
