Abstract

One embodiment of the present invention provides a system for facilitating establishment of connections between a local endpoint and a remote endpoint. During operation, the system sends, from the local endpoint, a single connection-request message to a proxy server, which forks the single connection-request message to a number of remote endpoints. The system receives one or more response messages from the remote endpoints. A respective response message carries address information associated with the remote endpoint. Upon receiving the response message, the system sends an acknowledgment corresponding to the received response message to the corresponding remote endpoint via the proxy server, and establishes a connection between the local endpoint and at least one remote endpoint.

First claim

What is claimed is:

1. A computer-executable method for facilitating establishment of a session initiation protocol (SIP) connection between a local endpoint and a plurality of remote endpoints of a remote device, the method comprising:
sending one or more packets, by the local endpoint, to at least one server according to session traversal utilities for network address translation (NAT) protocol;
determining, by the local endpoint, a type of firewall that the local endpoint is…
