System and method for interfacing legacy IP-PBX systems to SIP networks
First Claim
1. A data communications system integrating a voice switch adhering to a first protocol with a network of one or more first devices adhering to a second protocol, the system comprising:
- a server coupled to the voice switch and the network of one or more first devices, the server maintaining for at least one of the first devices a logical device adhering to the first protocol, the server further receiving media directed to the logical device and redirecting the media to the first device.

Abstract
A system and method for integrating a legacy IP-PBX to a session initiation protocol (SIP) network supporting one or more SIP sets. A SIP-PBX proxy server coupled to the legacy IP-PBX and the SIP network maintains a logical IP set for each SIP set on the SIP network. The logical IP set is configured to maintain IP-based signaling and media connectivity with the legacy IP-PBX. The SIP-PBX proxy server receives media directed to a logical IP set associated with a particular SIP set, and redirects the media to the particular SIP set. In doing so, the SIP-PBX converts messages that adhere to a private, vendor-specific protocol, to messages that adhere to the SIP protocol

6. In a data communications system including a voice switch adhering to a first protocol and one or more devices adhering to a second protocol, a server coupled between the voice switch and the one or more devices, the server comprising:
-
means for receiving from the voice switch a first message indicative of a first communication port to be used by one of the devices for receiving media;
means for receiving from the device a second message indicative of a second communication port to be used by the device for receiving the media; and
means for reconciling a difference between the first communication port and the second communication port. - View Dependent Claims (7, 8, 9, 10, 11, 12)
