4 Detailed service description
The web service provides a flexible way to provide multimedia message delivery and the dynamic management of the
media involved for the call participants. The interface is very simple, not requiring the developer to manage the creation
of the call.
The Audio Call web service allows media to be added/dropped for any ongoing call. This web service also allows
interaction with other call control web services (e.g. multimedia conference, third party call), enabling delivery of
multimedia to call participants in an ongoing call.
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: Call participants in a Call Session are anticipated to be uniquely identifiable using their URI address.
There are several mechanisms which may be utilized for the message content:
• Text, to be rendered using a Text-To-Speech (TTS) engine.
• Audio content (such as .WAV content), to be rendered by an audio player.
• VoiceXML, to be rendered using a VoiceXML browser.
• Video, to provide video streaming to the user.
• Capture media input from the end user.
The service may provide one or more of these mechanisms, as determined by service policy.
ETSI
---------------------- Page: 8 ----------------------
9 ETSI ES 202 504-11 V1.1.1 (2008-05)
The service allows application control of the call participants’ multimedia in a call:
• Allow multiple media types for each participant. In particular both audio and video as well as chat and data.
• Add and delete media types.
• Control the specific media stream direction (i.e. incoming, outgoing, bidirectional) for each media type.
• Get the current media status of a single call participant or for all the call participants in a call.
• Control the media interactions for a call participant.
A service policy determines if multimedia application control is supported.

Pattern: Request / response.
This example shows an audio message being played, and the different responses to status requests that occur at different
phases. Note that the last response, a service exception, reflects the transient nature of results, and that these results will
expire.

4 Detailed service description
The web service provides a flexible way to provide multimedia message delivery and the dynamic management of the
media involved for the call participants. The interface is very simple, not requiring the developer to manage the creation
of the call.
The Audio Call web service allows media to be added/dropped for any ongoing call. This web service also allows
interaction with other call control web services (e.g. multimedia conference, third party call), enabling delivery of
multimedia to call participants in an ongoing call.
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: Call participants in a Call Session are anticipated to be uniquely identifiable using their URI address.
There are several mechanisms which may be utilized for the message content:
• Text, to be rendered using a Text-To-Speech (TTS) engine.
• Audio content (such as .WAV content), to be rendered by an audio player.
• VoiceXML, to be rendered using a VoiceXML browser.
• Video, to provide video streaming to the user.
• Capture media input from the end user.
The service may provide one or more of these mechanisms, as determined by service policy.
ETSI
---------------------- Page: 8 ----------------------
9 Final draft ETSI ES 202 504-11 V1.1.1 (2008-02)
The service allows application control of the call participants’ multimedia in a call:
• Allow multiple media types for each participant. In particular both audio and video as well as chat and data.
• Add and delete media types.
• Control the specific media stream direction (i.e. incoming, outgoing, bidirectional) for each media type.
• Get the current media status of a single call participant or for all the call participants in a call.
• Control the media interactions for a call participant.
A service policy determines if multimedia application control is supported.

6.1 Play audio and check status
Pattern: Request / response.
This example shows an audio message being played, and the different responses to status requests that occur at different
phases. Note that the last response, a service exception, reflects the transient nature of results, and that these results will
expire.

4 Detailed service description
The web service provides a flexible way to provide multimedia message delivery and the dynamic management of the
media involved for the call participants. The interface is very simple, not requiring the developer to manage the creation
of the call.
The Audio Call web service allows media to be added/dropped for any ongoing call. This web service also allows
interaction with other call control web services (e.g. multimedia conference, third party call), enabling delivery of
multimedia to call participants in an ongoing call.
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: Call participants in a Call Session are anticipated to be uniquely identifiable using their URI address.
There are several mechanisms which may be utilized for the message content:
• Text, to be rendered using a Text-To-Speech (TTS) engine.
• Audio content (such as .WAV content), to be rendered by an audio player.
• VoiceXML, to be rendered using a VoiceXML browser.
• Video, to provide video streaming to the user.
• Capture media input from the end user.
The service may provide one or more of these mechanisms, as determined by service policy.

The service allows application control of the call participants’ multimedia in a call:
• Allow multiple media types for each participant. In particular both audio and video as well as chat and data.
• Add and delete media types.
• Control the specific media stream direction (i.e. incoming, outgoing, bidirectional) for each media type.
• Get the current media status of a single call participant or for all the call participants in a call.
• Control the media interactions for a call participant.
A service policy determines if multimedia application control is supported.

6.1 Play audio and check status
Pattern: Request / response.
This example shows an audio message being played, and the different responses to status requests that occur at different
phases. Note that the last response, a service exception, reflects the transient nature of results, and that these results will
expire.
