Last year, I’ve spent my spare time on upgrading my skills through an online training provided by The SIP School. These training mostly focus on Session Initiation Protocol although it extends relevant voice over IP protocols that had been commercially deployed in telecoms industry. I’ve written these blog as gesture of thanks to Graham Francis, CEO of The SIP School for providing such a cost effective training that is beneficial for technical managers, engineers, technicians and sales personnel who aims to upgrade their skills through online training on their own pace. In addition, these training would be beneficial as well for developers and students who want to dig on SIP and have a profound knowledge of SIP. At the end of the training course, as an evaluation on what I have learned with, I’d took the certification exam with confidence and passed.
The course module structure was well organized, commencing from the SIP core which is the foundation of the course. Students simply can enroll and pay online, after which an acknowledgment email is sent through the student registered email address containing the order information and order summary. Further information of the course content can be found on their website at http://www.thesipschool.com/
Student has two options on either to pay for “Training and Certification” or “Certification test only” thereby training cost would depend on which among the selection student has chosen with. Passing the exam certification entitled the student as SIP School Certified Associate, SSCA® which is worth 16 CEC credits towards a BICSI Certification. In addition, SSCA® is officially endorsed by Telecommunications Industry Association, further information can be found on the following link;

The outcome of the training course enhance my job effectiveness and productivity which scope includes analyzing voice over ip related issues affecting performance on voip traffic. To supplement the knowledge of SIP, essentially, it’s a must to read the relevant RFCs. There are huge lists of relevant RFCs dealing with SIP and each element on SIP network. How the request and response SIP messages being handled within the element on the SIP network and how the messages traverse on each element on the SIP network. SIP signaling and media issue happens frequently due to the rapid adaption of this protocol in telecommunication and infocom industry. In fact the volume of voice traffic nowadays originates from SIP user agents and traverses onto SIP network. With the deployment and adaption of LTE and WIMAX on tier1 mobile service providers, IP-PBX on corporate and government sectors, SIP would be a celebrity protocol on the next decades.
Describing briefly, SIP stands for Session Initiation Protocol an application-layer control (signaling) protocol for creating, modifying, and terminating sessions with one or more participants. These sessions include Internet telephone calls, multimedia distribution, and multimedia conferences. It was drafted by IETF Network Working Group and known as RFC 3261.
