Patent ID: 8312169

Claim:
A method for establishing a media session path, comprising: receiving a message from a first endpoint that includes a list of one or more network addresses, wherein the first endpoint is an alternative network address type (ANAT) endpoint; determining a preferred network address from the one or more network addresses based on a first preference of the first endpoint; obtaining a list of one or more candidates used by a second endpoint to traverse network address translation (NAT) network devices, wherein the second endpoint is an interactive connectivity establishment (ICE) endpoint; determining a corresponding candidate address from the one or more candidates based on the first preference; and transmitting a first message to the first endpoint and a second message to the second endpoint, the first message defining a corresponding candidate address and the second message defining the preferred network address, the corresponding candidate address and the preferred network address being operable to be used to establish a media session path between the first endpoint and the second endpoint.
