14 VoIP Basics

15 VoIP Call > SIP Negotiates RTP parameters (through SDP) Authentication > RTP carries audio stream in small packets 15

16 SIP Call Flow 16

17 Session Initiation Protocol > Similar to HTTP Plain Text protocol Request/Response Based > Sample request: INVITE SIP/2.0 Via: SIP/2.0/UDP pc33.jboss.com;branch=z9hg4bkkjshdyff To: «Anakin» From: «Jean» Call-ID: 987asjd97y7atg (like a Web Session ID) CSeq: INVITE... <SDP> 17

18 SIP - Requests > INVITE make a call > CANCEL cancel a call > BYE end a call > SUBSCRIBE to subscribe SIP events, such as buddy status update > REGISTER submit your contact info to the server > MESSAGE send a text (or other) message > OPTIONS query capabilities 18

19 SDP Session Description Protocol > Describing multimedia session v=0 o=sender IN IP s=a conversation c=in IP t=0 0 m=audio 7078 RTP/AVP a=rtpmap:0 PCMU/8000/1 a=rtpmap:8 PCMA/8000/1 a=rtpmap:3 GSM/8000/1 a=rtpmap:101 telephone-event/8000 a=fmtp:

20 Mobicents Overview

21 Mobicents 2.0 Overview > JBoss is the only vendor supporting both JSLEE and SIP Servlets 21

22 Mobicents Deployment Scenario 22

23 Market Segments > Big mobile and landline telecoms adopting IP/IMS infrastructure (performance, HA, service exposure) > Call centers (HA, UI convenience, BPM) > Classic web applications (easy development) Web shopping and customer service Social, banking, security, etc > Enterprises (integration, customization) PBX and unified communications Office application integration 23

24 Mobicents SIP Servlets

25 SIP Servlets in Java EE Architecture 25

26 Focus of SIP Servlets > Converged HTTP and SIP Applications > (Mobicents-specific beyond JSR-289) Media playback, record, conferencing, IVR, TTS and others, JSR 309 support (JSR 309) Diameter Base, Sh, Ro, Rf Tooling - JBCP Developer Studio SIP Servlets Plugin Integrated with Rich Web UI frameworks for Desktop-like experience support for Ajax and Comet-enabled frameworks Seam, Richfaces, GWT, Tomcat AIO, Jruby/Rails Telco Frameworks - Seam Telco Framework, Jruby Torquebox Telco Framework, Echarts For Sip Servlets Framework, JAIN SLEE Interoperability Patterns > Need anything else? It's on a case-by-case basis, but JAIN SLEE is the general solution. 26

27 Production Features > IMS & Diameter support > Congestion Control > Concurrency Control > Enterprise Monitoring with JBoss ON (Sip Servlets Plugin) > HA Support SIP Load Balancer bundled with JBCP SIP Servlets IP Load Balancer support with Red Hat Cluster Suite or any other IP LB SIP Session & Application Session Clustering nicely integrated with existing HTTP clustering Fine-grained control replication options Support for Mid Call Failover with bundled SIP LB or early dialog with IP LB Support for Converged Failover with apache http + Mod_jk 27

28 Mobicents JAIN SLEE

29 JAIN SLEE - Concepts > Geared towards Telco > SLEE = Service Logic Execution Environment High throughput, low latency event processing High performing platform for event driven applications > Asynchronous & Event Orientated > Network Abstraction Layer 29

30 JAIN SLEE Example 30

31 Mobicents JAIN SLEE Server > Integrated Java EE + JAIN SLEE environment > Network abstraction layer - SIP, XMPP, Diameter, Media/MGCP, HTTP, SMPP > Tooling - JBCP Developer Studio JAI N SLEE Plugin > Enterprise Monitoring with JBoss ON (JAIN SLEE Plugin) > High Performance and High Availibility 31

32 Mobicents Media Server

33 Mobicents Media Server > Handles Media processing to Deliver competitive, complete, best-of-breed, high quality media gateway > Provides a Component model, very flexible SIP Phone #1 RTP SIP Servlets / JAIN SLEE Container MGCP Mobicents Media Server SIP Phone #2 RTP 33

34 Architecture > Ann(ouncement) Endpoint: Allows playback for announcements in wav files. > Interactive Voice Response: Allows playback for announcements and tones, listen for DTMF events or voice messages. Allows recording. > Conference Bridge: provide access to a specific conference where calls are mixed. > Packet Relay: specific form of conference bridge with only two sockets > SS7 endpoints for interface with legacy networks > Custom Endpoint : Flexibility to define your own media path > Pure Java Implementation > Control the Media Server MGCP, JSR-309 API (uses MGCP under the covers) 34

35 Features > Media control MGCP (RFC 3435), Java Media Control API(JSR-309) > Supported Media Files Media files *.wav (G711, GSM, PCM), *.spx(speex), *.gsm > Media bearing/audi Codecs RTP formats: G711, G729, GSM, SPEEX, PCM 16bit 8-44kHz (Mono/Stereo) > Video any ISO Based format (.3GPP,...), H263 > SS7 support - ISUP : Signaling and Voice, INAP, MAP, CAMEL > Text To Speech > DTMF Recognition > Performance 200 Full Duplex connections: CPU usage less than 15% and maximum jitter less than 6ms 35

36 Mobicents SIP Presence

37 SIP Presence Service PUBLISH > Provides presence functionalities to SIP-based networks using standards developed by the IETF, OMA, 3GPP and the ETSI SUBSCRIBE / NOTIFY 37

38 Implementation 38

39 Mobicents Diameter

40 Mobicents Diameter Architecture 40

41 Features > Core Stack : Own fork of JDiameter open source stack Multiplexer + Customizable Validator (message validation) + Customizable Dictionnary (provide dictionnary of AVP to applications) > Interfaces Base : responsible for managing connection between peers and provide basic Authentication, Accounting and Session Management Sh (Client/Server) : managing User Data in HSS CCA: enable credit session management, and convey sufficient information for applications to perform charging activities. Ro/Rf : Online/Offline charging Cx/Dx : interaction between SIP IMS Proxies and HSS > Example applications (both for JSLEE and J2EE) Base and Mobicents SIP Servlets Event Call Charging Sh (Client/Server) and OpenIMS Integration Ro/Rf example > Enterprise Monitoring with JBoss ON (Diameter Plugin) 41
