ABSTRACT:
A method and system for network based call-pickup is provided. In one embodiment a first user agent communicates in a communication session with a second user agent in a network telephony system. The second user agent may request that a third user agent replace the second user agent in the communication. The third user agent may be a park server, and when it replaces the second user agent, the communication session may thereby be parked at the park server. A fourth user agent may then request that the third user agent (e.g., park server) initiate a communication session between the first user agent and the fourth user agent. The third user agent may then instruct the first user agent to communicate with the fourth user agent. The parked communication session may thereby be picked up by the fourth user agent.
