Plug and play provisioning of voice over IP network devices

摘要

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.

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.
