1. A method comprising:
- sending from a network device client to a dynamic host configuration protocol (DHCP) network configuration server a DHCP request message configured to request call configuration parameters to allow the network device client to operate as a source node or destination node for packet switched network telephony activity, wherein the network configuration server is configured to provide network configuration parameters for the network device client to communicate over a packet switched network and to retrieve the call configuration parameters from a session initiation protocol (SIP) call provisioning server, and wherein the DHCP request message is configured to request vendor-specific information in order to provision a call agent for a corresponding signaling protocol;
receiving at the network device a response message including the call configuration parameters from the network configuration server, wherein the call configuration parameters include a first telephone number for inter-office communication and a second telephone number for intra-office communication, and wherein the call configuration parameters comprise SIP user agent provisioning information; and
passing the call configuration parameters to the call agent in the network device client in order to configure the network device client to operate as the source node or the destination node for packet switched network telephony activity, wherein the call configuration parameters configure the network device client to receive inter-office communication via the first telephone number and to receive intra-office communication via the second telephone number; and
provisioning the call agent using the SIP user agent provisioning information.

Abstract
Techniques are provided for sending from a client in a network device a request message configured to request configuration parameters to allow the network device to operate as a source or destination node for packet switched network telephony activity. In response to receiving the request message, sending the configuration parameters from a server configured to retrieve the configuration parameters from a call provisioning server. The configuration parameters are received at the client and passed to a call agent in the network device in order to configure the network device to operate as a source or destination node for packet switched network telephony activity.

7. An apparatus comprising:
-
a processor; an interface configured to enable communication over a network; and a memory configured to store software instructions that when executed by the processor cause the processor to perform a call agent function and a client function, and instructions that, when executed by the processor, cause the processor to; send a dynamic host configuration protocol (DHCP) request message from the client function to a DHCP network configuration server configured to request call configuration parameters, wherein the network configuration server is configured to provide network configuration parameters for the apparatus to communicate over a packet switched network and to retrieve the call configuration parameters from a session initiation protocol (SIP) call provisioning server, and wherein the DHCP request message is configured to request vendor-specific information in order to provision a call agent for a corresponding signaling protocol; receive a response message to the request message from the network configuration server comprising the call configuration parameters, wherein the call configuration parameters include a first telephone number for inter-office communication and a second telephone number for intra-office communication, and wherein the call configuration parameters comprise SIP user agent provisioning information; pass the call configuration parameters to the call agent in order to configure the apparatus to operate as a source node or a destination node for packet switched network telephony activity, wherein the call configuration parameters configure the apparatus to receive inter-office communication via the first telephone number and intra-office communication via the second telephone number; and provision the call agent using the SIP server address and SIP user agent provisioning information. - View Dependent Claims (8, 9, 10, 11, 12)

13. Logic encoded in one or more storage devices for execution and when executed operable to:
-
send from a client in a network device a dynamic host configuration protocol (DHCP) request message to a DHCP network configuration server configured to request call configuration parameters to allow the network device to operate as a source or destination node for packet switched network telephony activity, wherein the network configuration server is configured to provide network configuration parameters for the network device to communicate over a packet switched network and to retrieve the call configuration parameters from a session initiation protocol (SIP) call provisioning server, and wherein the DHCP request message is configured to request vendor-specific information in order to provision a call agent in the network device for a corresponding signaling protocol; receive a response message from the server at the client in the network device, wherein the response message comprises the call configuration parameters from the network configuration server , wherein the call configuration parameters include a first telephone number for inter-office communication and a second telephone number for intra-office communication, and wherein the call configuration parameters comprise SIP user agent provisioning information; and pass the call configuration parameters to the call agent in the network device in order to configure the network device to operate as a source node or a destination node for packet switched network telephony activity, wherein the call configuration parameters configure the network device to receive inter-office communication via the first telephone number and receive intra-office communication via the second telephone number. - View Dependent Claims (14, 15, 16, 17, 18)
