HP OpenCall Media Platform
The HP OpenCall Media Platform 4.0 is a scalable, carrier-grade IP
multimedia server and MRF (Media Resource Function) deploying audio
and video services for multimedia portals, multimedia messaging,
conferencing and other advanced multimedia applications

What HP OCMP Can Be Used For?
Service Node:
The HP OpenCall Media Platform hosts the complete application, and may
initiate outgoing calls, bridge incoming calls, and/or initiate conferences.
With a SIP Application Server:
In an NGN or IMS network, the HP
OpenCall Media Platform is
deployed with a SIP application
server. In this case, the platform
provides the Media Resource
Function (MRF) or Media
Resource Function Processor
(MRFP).

Standard Components and Interfaces
OpenCall Media Platform is based on standard components and
interfaces:
 Commodity computer platforms such as Intel/AMD, running
industry-standard Linux environments.
 The standard interfaces are: SIP, RTP, RTSP, RTCP, MRCP,
VoiceXML, CCXML, netann and MSCML.
 Major IMS and NGN standards: 3GPP, 3GPP2 and TISPAN.

The Architecture of the Media Platform II.
 Base subsystem

Integrated telephony subsystem that provides an abstraction of the telephony
interfaces to the BRE subsystem.
 Audio subsystems, such as player and recorder resources, and connects to
ASR and TTS servers using the Media Resource Control Protocol (MRCP).
 BRE subsystem

OCMP-VoiceXML: fetches and compiles VoiceXML pages into dialogs, builds
the dialog state machine, and executes it.
 OCMP-CCXML: performs call control functionality
 Call Out Manager: call scheduling
 ASR and TTS: The ASR and TTS functions provide Automatic Speech
Recognition and Text-To-Speech synthesis

Rich-Call appliation at BME:
Cinema ticket prepay service
Aim: help the user through the procedures of buying a ticket in an interactive
way (i.e. watching movie trailers)
1. User calls the service
2. Gets access to a voice menu
3. Selects (using DTMF keys)
1.

7.
Which day of the week she prefers
Which film is she is interested in
Obtains automatically the videotailer of the movie
Chooses whether or not to buy a ticket for this movie
Press the DTMF key 0 to buy the ticket
Selects
1.
2.
Which room number she prefers
What are her 8 character identifier and 4 character PIN codes
8. Transaction initiated
9. Call is terminated by the service
