    • Voice services quality and measurement standards (MOS, etc.),
    • Real-time services in ATM, Frame Relay and IP networks (RTP/RTCP),
    • Voice compression (linear prediction, G.72x codecs) and packetization,
    • VoIP signaling overview (call control, media negotiations, mobility management),
    • VoIP standards evolution,

    • H.248 overview,
    • SIP overview: history, standard evolution.
  2. SIP Fundamentals
    • SIP main architecture,
    • SIP components (servers and clients) and their functions: SIP user agents (AU client and server),
    • SIP servers: proxy (stateful and stateless), redirect, registrar,
    • SIP location servers,
    • SIP gateways,
    • SIP message structure,
    • SIP requests and response codes,
    • SIP supporting IETF protocols (SAP, SDP),
    • SIP sessions: session setup, proxying and redirecting requests, address resolution, media negotiation via SDP.
  3. SIP Advanced Features
    • Call state in SIP Servers,
    • Call flow analysis,
    • SIP to PSTN interworking - SIP for Telephones (SIP-T),
    • SIP security,
    • QoS issues (call setup time, IP QoS),
    • The firewall and NAT problem.
  4. Services and Applications based on SIP.
    • SIP based end-user services,
    • Service creation possibilities with SIP,
    • Overview of SIP-CGI, CPL, Java servlets, Jain, Parlay, SIP for J2ME, SIP and SOAP, SIP and VoiceXML,
    • Instant messaging and presence with SIP.
  5. SIP in 3G Mobile Systems

    • IP Multimedia Subsystem (based on SIP) architecture (components),
    • IMS services,
    • 3GPP extensions to SIP,
    • IMS call routing scenarios,
    • IMS and QoS.
  6. SIP Final Remarks
    • Standardization trends - RFC’s and Internet-Drafts (IETF SIPPING workgroup),
    • SIP vs. H.323 (performance, robustness, security),
    • SIP deployment rules,
    • SIP deployment status,
    • SIP open issues.

Course Objectives

The Session Initiation Protocol (SIP) is an application-layer signaling protocol used for establishing multimedia sessions (typically VoIP) in an IP network. It is relatively simple protocol having been developed purely as a mechanism to establish sessions. It can be used as a signaling protocol for conferencing, telephony, presence and instant messaging. It is seen as a fundamental protocol for multimedia communication in packet networks. This technical, 2-days long SIP training seminar provides a high-level overview of SIP based systems and functionality. It is recommended for the technical staff with basic knowledge of wired and wireless telecommunications systems. The seminar will start with some generic VoIP issues and will focus on multimedia platforms based on the SIP protocol.

Pre-requisites

There are no prerequisites to attend the course, but basic knowledge about IP would be beneficial.

Training Structure

Two days training divided into logical sessions.

Methodology

Instructor led training.
