First Claim
1. A method for dynamically establishing links between a plurality of Internet Protocol (IP) Private Branch Exchanges (PBX) in a communication network, comprising:
- receiving an incoming link setup signaling message from an originating IP PBX; and
processing said link setup signaling message to dynamically establish a virtual link between said originating IP PBX to a terminating IP PBX.

Abstract
A method and apparatus for enabling a packet network provider, e.g., a VoIP network provider to provide virtual tie lines that give enterprise users of IP PBXs dedicated bandwidth on an as-need basis are disclosed. The present method defines a structure for creating signaling messages from the IP PBX to the edge of the provider'"'"'s network that request the immediate use of dedicated paths for creating voice paths for intra enterprise users across a wide area network. Once these dedicated paths are established, the subscribers enjoy the same quality of service that is provided by dedicated tie lines. When the established tie lines are no longer in use or needed, they will be released and hence provides cost savings to the subscribers.
