Claim:
A method for providing unauthenticated client access to session initiation protocol (SIP) communication services provided by an Ethernet device comprising a proxy and a conference bridge, comprising: receiving, by a device installed as an Ethernet adapter, a SIP call request from a first client, the SIP call request comprising a first uniform resource identifier (URI), the first URI comprising a SIP alias; determining, by the device, that the first client has not been authenticated; identifying, by the device, that the first URI comprises a SIP alias; proxying, by the device, the SIP call request to an endpoint associated with the SIP alias, responsive to the identification of the first URI as a SIP alias; receiving, by the device, a second SIP call request from the first client, the SIP call request comprising a third URI; and blocking, by the device, the second SIP call request.
