1 Scope
The present document is part 2 of the Stage 3 Parlay X 3 Web Services specification for Open Service Access (OSA).
The OSA specifications define an architecture that enables application developers to make use of network functionality
through an open standardized interface, i.e. the OSA APIs.
The present document specifies the Third Party Call Web Service. The following are defined here:
• Name spaces.
• Sequence diagrams.
• Data definitions.
• Interface specification plus detailed method descriptions.
• Fault definitions.
• Service Policies.
• WSDL Description of the interfaces.
2 References
References are either specific (identified by date of publication and/or edition number or version number) or non-
specific.
• For a specific reference, subsequent revisions do not apply.
• Non-specific reference may be made only to a complete document or a part thereof and only in the following
cases:
- if it is accepted that it will be possible to use all future changes of the referenced document for the
purposes of the referring document;
- for informative references.
Referenced documents which are not found to be publicly available in the expected location might be found at
http://docbox.etsi.org/Reference.
For online referenced documents, information sufficient to identify and locate the source shall be provided. Preferably,
the primary source of the referenced document should be cited, in order to ensure traceability. Furthermore, the
reference should, as far as possible, remain valid for the expected life of the document. The reference shall include the
method of access to the referenced document and the full network address, with the same punctuation and use of upper
case and lower case letters.
NOTE: While any hyperlinks included in this clause were valid at the time of publication ETSI cannot guarantee
their long term validity.

4 Detailed service description
Currently, in order to perform a third party call in telecommunication networks we have to write applications using
specific protocols to access Call Control functions provided by network elements (specifically operations to initiate a
call from applications). This approach requires a high degree of network expertise. We can also use the OSA gateway
approach, invoking standard interfaces to gain access to call control capabilities, but these interfaces are usually
perceived to be quite complex by application IT developers. Developers must have advanced telecommunication skills
to use Call Control OSA interfaces.
In this clause we describe a Parlay X 3 Web Service, Third Party Call, for creating and managing a call initiated by an
application (third party call). The overall scope of this Web Service is to provide functions to application developers to
create a call in a simple way. Using the Third Party Call Web Service, application developers can invoke call handling
functions without detailed telecommunication knowledge.
The underlying model of the service is based on the following entities:
• Call Session: a call (uniquely identified) to which participants can be added/removed.
• Call Participant: each of the call parties (uniquely identified) involved in the call session.
• Media: the call can utilize multiple media types to support the participants' communication. In particular both
audio and video streams are available, including the specific stream direction (i.e. incoming, outgoing,
bidirectional).
NOTE 1: Call participants in a Call Session are anticipated to be uniquely identifiable using their URI address.
An application setting up a call session must initially invoke the makeCallSession. The result of such invocation is the
creation of a "context" that represents a call session with usually two participants, or at a minimum one participant
connected; a unique identifier is assigned to the just-created call session. Subsequently the application may wish to add,
remove, park or transfer call participants. In order to do so the operations addCallParticipant,
transferCallParticipant, deleteCallParticipant can be used. Furthermore the call session or call participant status
including the media details can be read. In order to do so the operations getCallParticipantInformation, and
getCallSessionInformation can be used. It is also possible to retrieve only the media details using the
getMediaForParticipant or getMediaForCall operations of the Audio Call web service.
The application can also force the call session and all its participants to be terminated with the operation
endCallSession.

NOTE 2: A call session allows the application to avail of other web service features that can add value to the
created call session. For example the Audio Call web service can provide multimedia message delivery to
