Information technology — UPnP Device Architecture — Part 26-10: Telephony device control protocol — Level 2 — Call management service

ISO/IEC 29341-26-10:2017 is compliant with [1]. It defines a service type referred to herein as the CallManagement service. The CallManagement service is a UPnP service that allows control points to use the telephony features(e.g., voice call, video call, and data transfer etc.) provided by a Telephony Server (TS). The CallManagement service enables the following features to a Telephony Control Point (TelCP): - start an outgoing call - accept an incoming call - modify the capability of an existing call (e.g., changing from a voice call to a video call) - terminate a call - preview call logs - register a call back and check the availability of the registered call back To realize these features, the CallManagement service manages the connectivity of calls and media streams.

Foreword
ISO (the International Organization for Standardization) and IEC (the International
Electrotechnical Commission) form the specialized system for worldwide standardization.
National bodies that are members of ISO or IEC participate in the development of
International Standards through technical committees established by the respective
organization to deal with particular fields of technical activity. ISO and IEC technical
committees collaborate in fields of mutual interest. Other international organizations,
governmental and non‐governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical
committee, ISO/IEC JTC 1.
