2 What is the Dialogic IP Media Server? The Dialogic IP media server is a SIP and other open standards based software only media processing platform for voice and video running on Linux and COTS x86 servers. Slide 3

3 Real world deployments IT Austria it-austria is the joint data center of Bank Austria, Erste Bank and the Austrian savings banks. Replacement of Nortel DMS, HP IN and Periphonics IVR s 11 IMG gateways 3 Media servers Call centers IVR for End user self management Slide 4

4 Real world deployments Amazon.com Call center based on IPMS Own development by in house IT department IPMS is used for announcement playback and music on hold in queues Slide 5

5 Real world deployments Gintel/Network Norway Gintel is a former Telenor R&D division Network based PBX Application resides on an Oracle OCCAS server IPMS is used for announcement playback and conference mixer Network connectivity currently via IMG gateways Solution supports Camel and INAP for larger scale installations Slide 6

6 Real world deployments -- Telenor Telenor Group provides telecommunication services in 13 countries across Europe and Asia. IPMS is used as the Media Resource Function in the Telenor Playground. Applications are typically implemented on Oracle OCCAS or on an HP SDP Playground has 70+ services, and is used as a testing ground by all Telenor operating companies IPMS is currently used for Virtual PBX and sponsored calling services. Slide 7

7 Real world deployments Fokus Fraunhofer One of the major telecoms research institutes in Europe IPMS is the MRF in the Fokus IMS lab Used in a multitude of applications like: Facebook mashups FMC applications Video conferencing solutions Fokus does a lot of consulting for tier-1 telecoms operators worldwide Slide 8

8 What is an IP Media Server? Execution of Media Resources Voice and Video Play Back / Record DTMF detection Conference mixing Video transcoding Fax Enabling the delivery of voice and video Applications Media Resource Function (MRF) IVR and IVVR Conferenceing Announcements IP Contact Centers and IVVR Mobile Radio Unified Messaging Dialogic: IP Media Server Video SMS Sponsored Calling Color Ring Back Tone Slide 11

9 What is an IP Media Server? SIP Application Server User Directory Database IP RTP SIP VoiceXML MSCML HTTP Message store Content Server H.263 G.711 or (video) (audio) IP Media Server Application Server Contains Call Control logic Controls the media server via SIP and VoiceXML, MSCML or NetAnn IP Media Server Transports media via RTP, HTTP, NFS Fetches VoiceXML pages Slide 12

10 Role of the SIP Application Server Hosting applications on SIP Application Servers (SIP AS) Contains application logic and manages the call control Controlling Media Resources on the IPMS via SIP Might use other standard based inerfaces like SIP Servlets (JSR289) or Java Media Server Control (JSR309) Manages SIP network sessions SIP application servers are not bundled with the Dialogic IP Media Server. Dialogic refers to 3 rd party vendors or Open Source SIP AS products Slide 13

13 Integration Interfaces and application development IP Media Server supports applications in open standards from multiple vendors on single platform VoiceXML, web based application development MSCML, Specialized for conferencing services Netann, Network Announcements with little user interaction MRCP supporting Speech recognition and Text-to-Speech. VoiceXML allow seamless integration of Internet-based content into telecommunication services providing access to communication, entertainment and commerce. Maximize reuse and flexibility Reduce implementation cost by cheaper software development Convert web based services in telephony applications and vocal dialogues Unity of web and voice channels sharing business logic Web developers familiar with XML start right away Separation of call control and user interface Availability of 3 rd party drag-drop VoiceXML Software Development Tools Slide 16
