Explore how a SIP session is established through a multi-proxy call flow, from invite to 200 OK, including DNS discovery, registrar lookups, and media setup.
Learn how SIP negotiates media using SDP, matching codecs between peers, exchanging invite and 200 OK, and establishing RTP streams, with update and re-invite for call modifications.
Explore how SIP proxies route calls via stateless and stateful servers, using via and record-route headers for call routing, forwarding, and path preservation.

Explore SIP diversion header for call redirection and routing, learn call park and pickup workflows, and review presence and instant messaging with SIMPLE, plus SIP-based conferencing.
Explore how sip works in IP based networks, combining signaling with SDP payload, RTP media streams, and codecs like G 7-Eleven and G729, and contrast TCP, UDP, and TLS transport.
Explore how sip signaling and rtp media traverse nat, detailing sip registration, nat bindings, keepalives, and media routing via sdp and proxy, with practical sip and nat traversal examples.
Examine the SIP and NAT traversal call flow for a user agent behind NAT, including NAT proxy, RTP relay, and gateway interactions, with SDP modifications and 200 ok signaling.
Explore SIP firewalls and ACL protections, controlling SIP signaling flow across proxies and gateways, securing ports 5060, 5061, and 5068 with carrier IP restrictions, while improving quality of service.
Explore sip authentication methods and secure signaling with tls, digest authentication using md5, nonces, and call flow examples, including Cisco Unified Border Element.
Learn how the tls handshake secures sip signaling, from client hello to session keys and encrypted sip messages. Compare tls, s/mime, and ipsec approaches and discuss tradeoffs.
Explore sip message encryption using tls and secure rtp to protect signalling and media in sip trunking, including certificate authentication, tls ports 5061 and 5004, and best practices.
protects against sip-based attacks like flooding and spoofing. learn how registration and call floods exhaust proxy servers and disrupt legitimate calls, and how idps and encryption mitigate these dos threats.
Explore SIP user agents and proxies, including UAC and UAS roles, proxy forking, stateless and stateful proxies, and how trunks, gateways, and troubleshooting fit into SIP deployment.
Explore SIP server deployment and configuration across vendors, install the office sip server on Windows, manage domains, users, messaging, auto attendant, phone menu, and business hour rules.
Explore configuring SIP trunks and gateways, register trunks, and set up outbound and inbound routes across PBX and vendor platforms (S-series, Ribbon SBC, Twilio, AudioCodes).
Learn to troubleshoot SIP issues by diagnosing registration, compatibility with PBX systems, and bandwidth and codec problems, using packet captures, endpoint testing, and NAT traversal remedies.
Explore the benefits and challenges of SIP over IPv6, including scalable addressing, improved security, mobility, and QoS, and how dual-stack proxies and RFCs 3263, 3264, 6157 enable transitions.
Explore SIP for multimedia communication, including video conferencing and WebRTC integration, enabling vendor agnostic unified collaboration across desk phones, soft phones, and browsers.
Explore advanced SIP features and extensions, including private extensions for asserted identity, privacy controls, and message methods described in RFCs, with registration and call-flow examples.
Celebrate completing eight modules of the SIP course, covering SIP basics to advanced call flows, authentication, registration, RFC, ITU-T, and IETF standards, and vendor-specific implementations.
Become a SIP professional and learn one of employer's most requested skills nowadays!
This comprehensive course is designed so that IT consultants, contact center staff, support engineers, support analysts on Telephony companies... can learn SIP (Session Initiation Protocol) from scratch to use it in a practical and professional way. Never mind if you have no experience in the topic, you will be equally capable of understanding everything and you will finish the course with total mastery of the subject.
After several years working in VoIP, we have realized that nowadays mastering SIP for signaling and controlling interactive communication sessions is very necessary in VoIP, Contact Centers or other IT networks applications. Knowing how to use this tool can give you many job opportunities and many economic benefits, especially in the world of VoIP.
The big problem has always been the complexity to perfectly understand SIP requires, since its absolute mastery is not easy. In this course we try to facilitate this entire learning and improvement process, so that you will be able to carry out and understand your own projects in a short time, thanks to the step-by-step, detailed and hands-on examples of every concept.
With almost 8 exclusive hours of video, this comprehensive course leaves no stone unturned! It includes both practical exercises and theoretical examples to master SIP. The course will teach you how to initiate and terminate an IP communication session (for example voice calls or video conferences) in a practical way, from scratch, and step by step.
We will start with the setup of the needed work environment on your computer, regardless of your operating system and computer.
Then, we'll cover a wide variety of topics, including:
Introduction to SIP and course dynamics
Setup and general familiarization with the SIP work environment, architecture and components
SIP fundamentals: Requests and responses, transactions and dialogs, and SIP Uniform Resource Identifier (URI) and addressing
SIP Call Flow: User registration and authentication, Establishing a SIP session and Media negotiation and session description
Mastering SIP Services and Features
SIP in IP-based Networks: VoIP, NAT traversal and firewalls
Security and Authentication methods in SIP
SIP Implementation and Configuration: SIP user agents (UA), proxies, SIP server deployment and SIP trunks and gateways
SIP Troubleshooting, Future Trends and Advanced SIP features and extensions (RFCs)
Mastery and application of absolutely ALL the functionalities of SIP
Practical exercises, complete projects and much more!
In other words, what we want is to contribute our grain of sand and teach you all those things that we would have liked to know in our beginnings and that nobody explained to us. In this way, you can learn to build and manage a wide variety of projects and make versatile and complete use of SIP. And if that were not enough, you will get lifetime access to any class and we will be at your disposal to answer all the questions you want in the shortest possible time.
Learning SIP has never been easier. What are you waiting to join?
