Abstract

Approaches for provisioning phones in packet voice networks (10) are disclosed. One approach comprises determining that an Internet Protocol phone (12 A,B,N) has registered in a network (24); receiving a unique identifier of the IP phone; determining, based on the unique identifier of the IP phone, a user identifier of an individual user associated with the IP phone; generating a configuration for the IP phone based on the user identifier; and providing the configuration to the IP phone (32). Various approaches for deriving a user identifier based on the unique identifier of the phone are disclosed.

Claims (4)

1. An apparatus providing automated provisioning of phones in a packet voice network, the apparatus comprising:
means for determining that an Internet Protocol (IP) phone has registered in a network;
means for receiving a unique identifier of the IP phone;
means for determining, based on the unique identifier of the IP phone, a user identifier of an individual user associated with the IP phone;
means for generating a configuration for the IP phone based on the user identifier;
and means for providing the configuration to the IP phone.
2. An apparatus providing automated provisioning of phones in a packet voice network, the apparatus comprising:
a network interface that is coupled to the data network for receiving one or more packet flows therefrom;
a processor;
one or more stored sequences of instructions which, when executed by the processor, cause the processor to perform:
determining that an Internet Protocol (IP) phone has registered in a network;
receiving a unique identifier of the IP phone;
determining, based on the unique identifier of the IP phone, a user identifier of an individual user associated with the IP phone;
generating a configuration for the IP phone based on the user identifier; and providing the configuration to the IP phone.
3. An apparatus as recited in claim 2, wherein the unique identifier of the IP
phone is a media access control (MAC) address; wherein each switch in the network is requested to provide a plurality of port identifiers corresponding to each port of said switch and a plurality of neighbor MAC addresses corresponding to each neighbor device that is coupled to each said port; wherein one of the port identifiers is selected based on matching the unique identifier of the IP phone to the neighbor MAC addresses; wherein a user identifier is selected, based on the selected port identifier, from a table that associates switch ports to users.
4. An apparatus as recited in claim 2, wherein the unique identifier of the IP
phone is a media access control (MAC) address; wherein an inventory system is requested to provide a plurality of port identifiers corresponding to each port of each switch in the network and a plurality of neighbor MAC addresses corresponding to each neighbor device that is coupled to each said port; wherein one of the port identifiers is selected based on matching the unique identifier of the IP phone to the neighbor MAC addresses; and wherein a user identifier is selected, based on the selected port identifier, from a table that associates switch ports to users.

4. An apparatus as recited in claim 2, wherein the unique identifier of the IP
phone is a media access control (MAC) address; wherein an inventory system is requested to provide a plurality of port identifiers corresponding to each port of each switch in the network, a plurality of neighbor MAC addresses corresponding to each neighbor device that is coupled to each said port, and a plurality of user identifiers that are associated with users of computers that correspond to at least some of the neighbor MAC addresses;
wherein one of the port identifiers is selected based on matching the unique identifier of the IP phone to the neighbor MAC addresses; and wherein one of the user identifiers is selected based on the selected port identifier.

6. An apparatus as recited in claim 2, wherein another device is coupled to the IP
phone; wherein discovery protocol neighbor information is retrieved from a network element to which the IP phone and the other device are coupled; wherein it is determined from the discovery protocol neighbor information that the other device is coupled to the same network element as the IP phone; and wherein the user identifier is obtained from the discovery protocol neighbor information.

7. An apparatus as recited in claim 2, wherein another device is coupled to the IP
phone; wherein network traffic passing through the IP phone and directed to the other device is monitored; and wherein the user identifier is obtained from the network traffic when the network traffic comprises packets of a protocol known to include user identifiers.

8. An apparatus as recited in claim 2, wherein the apparatus subscribes to events identifying registration of IP phones; and wherein a call controller in the network publishes the events.
9. An apparatus as recited in claim 2, wherein a call controller in the network is requested to provide information about all IP phones that are known to the call controller.
10. An apparatus as recited in claim 2, wherein a call controller in the network is requested to provide information about all IP phones that are known to the call controller;
and wherein a MAC address of each IP phone that is known to the call controller is received from the call controller.
11. An apparatus as recited in claim 2, wherein a stored basic configuration is selected based on the unique identifier of the IP phone and the user identifier, assigning a phone number, and assigning a feature set, to result in generating a final configuration.
12. A method as recited in Claim 11, wherein a call controller in the network is provisioned with the final configuration.
13. An apparatus as recited in claim 2, wherein the IP phone is registered at a call control system with a minimum configuration and a temporary number that is assigned from a pool of available numbers.
14. An apparatus providing automated provisioning of phones in a packet voice network, the apparatus comprising:
a network interface that is coupled to the data network for receiving one or more packet flows therefrom;
a processor;
one or more stored sequences of instructions which, when executed by the processor, cause the processor to perform:
determining that an Internet Protocol (IP) phone has registered in a network;
assigning a unique temporary phone number to the IP phone;
receiving a media access control (MAC) address of the IP phone;

identifying a port of a switch in the network that is coupled to the IP phone;
when a mapping of switch ports to user identifiers is unavailable in the network, using discovery protocol neighbor information to identify another device that is coupled to the same port as the IP phone, and obtaining a user identifier from the discovery protocol neighbor information when such other device is identified;
when a mapping of hostnames to user identifiers is unavailable in the network:
monitoring IP traffic passing through the IP phone and directed to the other device;
obtaining the user identifier from the IP traffic when the IP traffic comprises packets of a protocol known to include user identifiers;
retrieving, from a database of user information, a user record based on the user identifier;
obtaining a user phone number from the user record; and provisioning the IP phone with a final configuration that includes the user phone number.
15. An apparatus as recited in Claim 14, wherein a final configuration is created that includes configuration information for one or more feature sets specific to a user associated with the user identifier.
