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.
