3712 Cisco CCNA Syllabus in 5 Days 35 hours A 5 day practical networking course designed to familiarise students with Cisco IOS (version 12). The course details the key commands used to configure and secure Cisco routers and switches, and covers the CCNA syllabus - including wired and wireless LAN access. Students will inter-connect networks by implementing static routes, distance-vector and link-state based dynamic routing protocols. The devices will be configured to route traffic across LAN/VLAN//WAN boundaries, by encapsulating datagrams across serial data links using various WAN protocols, such as HDLC, Frame Relay, ISDN and PPP (with CHAP authentication). VLAN encapsulation/tagging will be via IEEE802.1Q/P. Standard and Extended Access Control Lists will be configured and applied to router interfaces to filter traffic based on IP address and/or traffic type. Students will configure static and dynamic NAT to route between private and public networks and cover the theory of Virtual Private Networks (VPN's) Students will copy router configurations and IOS images to/from a TFTP Server. Privileged commands will be used to debug TCP/IP protocols to ensure proper operation of the routers. Students will also perform password recovery operations. The course is primarily aimed at IP v4 but does give an overview of IP v6 addressing and covers migration from an IP v4 to an IP v6 network. Other protocols and technologies (VPN's / Wireless) may be demonstrated if time permits. Course can be customised to precise requirements of customer. Audience: This course is suitable for anyone looking for a basic understanding of internetworking with Cisco devices and covers the CCNA syllabus. Course is approximately 50% practical Objectives: At the end of this course the student will be able to configure Cisco routers to: Inter-connect networks using static routes Inter-connect networks using RIP, OSPF and EIGRP.

sipvoip SIP protocol in VoIP 21 hours The course consists of two complementary parts – a theoretical and a practical one. The first is a one day introduction covering motivation, philosophy, fundamentals and rules of operation of the SIP protocol and ways it is used to implement telecom services with focus on IP telephony and VoIP. The second two-day part enables participants to learn practical aspects of service operation within a framework of hand-on laboratory exercises giving detailed insight into configuration of components of SIP telephony architecture, SIP signalling at both message sequence chart and internal message structure levels, and assists in understanding of typical problems and troubleshooting including security and telecom fraud aspects. The trainers will share their experience in launching, operation and management of SIP telephony covering also virtualization and cloud based solutions. Practical part is presented using both SIP hardphones and softphones and IP telephony servers (Asterisk and Freeswitch). Participants can take advantage of the fact trainers have got rich technical and business experience in IP telephony and submit their own problems and questions. They will be included in the agenda at wrap-up as a supplement to the training to meet current urgent needs of clients. Training is addressed to participants with basic knowledge and experience in telecom services – specifically in VoIP and IP networking.  Part I: Introduction Introduction History and motivation Types of VoIP and its evolution SIP – main concepts SIP standardization (RFC 3261 and other relevant standards) Architecture UA – User Agent Predefined servers: Registrar, Location, Proxy and Redirect Application servers Identification and addressing SIP trapezoid Servers and their operation Registration  SIP server in Proxy and Redirect modes Stateless and stateful Proxy servers Location server SRV records and DNS uri/url/urn, ENUM and NAPTR records SIP signalling messages (including Instant Messaging & Presence – IMP extensions) Message structure Requests Responses Example of a call Headers and parameters IMP models SDP (Session Description Protocol) Description of media Standard list of codecs Session negotiation rules Call flows – SIP signalling SIP session – main  RFC 3261 example Sample call scenarios Conferencing and IP PBX Changing media during a session Using IMP Routing of SIP requests and responses VIA header ROUTE and RECORD-ROUTE headers SIP-PSTN interworking SIP-T and SIP-I SIP early media and SIP trunking SIP-PSTN signalling SIP – security problems Secure SIP, Secure RTP and Secure RTCP Typical implementations of Secure SIP Practical problems and perspectives NAT and firewall traversal QoS SIP and SDP in 3GPP IMS architecture Wrap-up and discussion Part II: Hands on SIP in LAN environment: XLite SIP UA + Asterisk Creating Asterisk accounts with a simple dial plan Configuration of XLite SIP UA (dtmf, codecs, nat, rtp, timer, register) and SIP phones (Polycom, Gigaset, Yealink, Linphone) Registration, initiating and receiving calls P2P calls with Linphone Analyzing of SIP signalling using Wireshark Configuration of a server Registration of SIP signalling and RTP media streams SIP packet analysis.
