First Claim
1. A method for establishing a voice over internet protocol conference call by joining a first voice over internet protocol station in a communication between a plurality of communication stations, wherein one of the plurality of communication stations is a second voice over internet protocol station in a private network and the first voice over internet protocol station is in the private network, the method comprising:
- receiving an indication at a voice conference server from the first voice over internet protocol station in the private network for joining one of a plurality of existing conversations on the voice conference server between the plurality of communication stations, wherein the voice conference server is located at an access point serving the first voice over internet protocol station, wherein the plurality of existing conversations comprises voice over internet protocol calls and each one of the plurality of existing conversations is on a different connection;
setting up a connection between the voice conference server and the first voice over internet protocol station;
receiving an identification of the one of the plurality of existing conversations on the voice conference server via a code number entered by the first voice over internet protocol station corresponding to the second voice over internet protocol station after the connection between the voice conference server and the first voice over internet protocol station is set up, wherein the one of the plurality of existing conversations is between the second voice over internet protocol station in the private network and a phone in a public network, wherein the voice conference server is external to the first voice over internet protocol station and the plurality of communication stations;
establishing a real-time transport protocol voice path with the first voice over internet protocol station and the voice conference server; and

Abstract
The present invention relates to a method and system for providing conference call services in a VoIP local network. A VoIP communication station may be conferenced into a VoIP call between at least two other communication stations. In one embodiment, a Voice Conference Server device (VCS) receives a “join-call’ signal or indication from a VoIP phone wishing to conference into a VoIP connection. The VoIP connection may be between at least one VoIP phone in a local network and a communication station such as a PSTN phone in a public network. The VCS sets up an RTP voice path and conferences in the VoIP communication station providing the “join-call” signal or indication.
