VoIP Basics
VoIP Call > SIP – Negotiates RTP parameters (through SDP) –
Authentication
> RTP – carries audio stream in small packets
15
SIP Call Flow
16
Session Initiation Protocol > Similar to HTTP –
Plain Text protocol
–
Request/Response Based
> Sample request:
INVITE sip:
[email protected] SIP/2.0 Via: SIP/2.0/UDP pc33.jboss.com;branch=z9hG4bKkjshdyff To: « Anakin » From: « Jean » ;tag=88sja8x Call-ID: 987asjd97y7atg (like a Web Session ID) CSeq: 986759 INVITE ...
17
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
SDP – Session Description Protocol > Describing multimedia session
v=0 o=sender 123456 654321 IN IP4 127.0.0.1 s=A conversation c=IN IP4 127.0.0.1 t=0 0 m=audio 7078 RTP/AVP 111 110 0 8 3 101 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:101 0-11

Mobicents Overview
Mobicents 2.0 Overview > JBoss is the only vendor supporting both JSLEE and SIP Servlets
21
Mobicents Deployment Scenario
22
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
Mobicents SIP Servlets
SIP Servlets in Java EE Architecture
25
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
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
Mobicents JAIN SLEE
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
JAIN SLEE Example
30
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
Mobicents Media Server
Mobicents Media Server > Handles Media processing to Deliver competitive, complete, best-of-breed, high quality media gateway > Provides a Component model, very flexible

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
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

Mobicents Diameter
Mobicents Diameter Architecture
40
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)
