Methods, devices, and systems for creating a call abstraction to enable an application to monitor and control various types of User Agents (UAs) are provided. The application may be adapted to monitor and control simple UAs that do not recognize out of dialog (OOD)-REFER signals as well as advanced UAs that do recognize and can respond to OOD-REFER signals.

Simultaneous advanced call control for both simple and advanced SIP user agents

Methods, devices, and systems are provided for enhancing the functionality of a communication device, such as a communication endpoint. This provides the ability to enhance less intelligent SIP endpoints with required features to support a richer user experience. Furthermore, the endpoint enhancer may be dynamically pluggable onto an existing network device. This provided pluggability allows a network administrator to add a new SEE template to the network without disrupting the network operation or the operation of previously existing SEEs.
