Abstract

In a method of registering an IP device in a network where one of a plurality of servers in the network has provided to the IP device an IP address for a controller for which the IP device has not been programmed, the improvement comprising accessing a database to obtain a further IP address for a designated controller for which the IP device has been programmed.

Claims

1. In 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 a 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 improvement 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.

2. The improvement of claim 1, wherein said accessing said database further 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.

3. The improvement of claim 1, wherein said database is replicated in each of said multiple PBXs.
