Patent Images
1. A method of registering an IP device programmed for a particular PBX in a network of multiple PBXs connected in clusters, said PBXs including respective servers and controllers, where one of said servers has provided to the IP device an IP address for one of said controllers in a further PBX for which the IP device has not been programmed, the method comprising:
- receiving a software ID from said IP device and in response accessing a database to obtain a further IP address for a designated controller in said particular PBX for which the IP device has been programmed, and redirecting said IP device to establish a connection with said designated controller for registering said IP device therewith;
wherein said accessing said database includes reading a first ID from said database using said software ID as a key to identify one of said clusters within said network containing said designated controller;
reading a second ID from said database using said first ID as a key to identify one of said multiple PBXs within said one of said clusters containing said designated controller; and
reading said further IP address for said designated controller from said database using said second ID as a key.

2. A method of registering an IP device programmed for a particular PBX in a network of multiple PBXs connected in clusters, said PBXs including respective servers and controllers, where one of said servers has provided to the IP device an IP address for one of said controllers in a further PBX for which the IP device has not been programmed, the method comprising:
-
accessing a database to obtain a further IP address for a designated controller in said particular PBX for which the IP device has been programmed, and redirecting said IP device to establish a connection with said designated controller for registering said IP device therewith; wherein said accessing said database includes;
reading a cluster element ID from a remote directory number (DN) table in said database using a software ID supplied by said IP device as a key, wherein said cluster ID identifies one of said clusters within said network containing said designated controller;
reading a PBX signalling ID from a cluster table using said cluster element ID as a key, wherein said PBX signalling ID identifies one of said multiple PBXs within said one of said clusters containing said designated controller; and
reading said further IP address for said designated controller from a PBX controller table using said PBX signalling ID as a key. - View Dependent Claims (4)
