In this course, you will learn how VoIP systems like Skype work and implement your own app for voice calls and text messages. You will start by using the Session Initiation Protocol (SIP) for session management. Next, you will learn how voice codecs such as Adaptive Multi Rate (AMR) are used in 3G networks and use them for voice traffic in your app.
Learning Goals: After completing this course, you will be able to:
1. Implement session initiation, management and termination on your DragonBoard™ 410c using SIP.
2. Discover other users and exchange device capabilities.
3. Compare and contrast narrowband and wideband codecs and experience the voice quality differences between them.
4. Implement and demonstrate VoIP calls using the DragonBoard 410c.

Reviews summary
Hands-on iot communication with voip
According to learners, this course offers a highly practical deep dive into IoT communication, particularly focusing on VoIP systems and associated protocols. Many appreciated the hands-on opportunity to build a VoIP application using Android Studio and the DragonBoard 410c, calling it a valuable skill development experience. However, some found the reliance on specific hardware (DragonBoard 410c) and assumed prior knowledge of tools like Git and ADB to be a potential barrier, requiring additional setup effort. The explanations of SIP and codecs are generally well-received for their clarity, providing a strong foundation for those with the necessary technical background.
Directly applicable insights into IoT communication.
"The course perfectly aligned with my goal of understanding how IoT devices communicate effectively in various scenarios."
"It's a crucial next step after the sensing course, truly showing how 'things' interact and exchange information."
"I gained valuable insight into conveying latency-sensitive data, which is highly relevant for my work in IoT applications."
Well-explained SIP, codecs, and IoT communication protocols.
"The modules on SIP and codecs were very clear and provided a solid understanding of these communication technologies."
"I found the explanations of how VoIP works in a nutshell to be very insightful and easy to follow, even for complex topics."
"Professor Garudadri's lectures on codecs effectively demystified complex audio compression techniques used in networks."
Valuable hands-on experience building a VoIP app.
"The most valuable part was building my own VoIP application; it truly solidified the concepts learned."
"I appreciated the hands-on approach to implementing SIP and codecs; it made the theory concrete and applicable."
"I gained practical skills directly applicable to how IoT devices communicate in real-world scenarios."
Requires familiarity with Android Studio, Git, and ADB.
"Coming into this, I wish I had brushed up more on Android Studio and Git; it was a steep learning curve at times."
"The course assumes you're already comfortable with tools like ADB and fastboot, which wasn't always the case for me."
"While the core concepts are explained clearly, the practical setup requires solid familiarity with the development environment tools."
Course relies on specific, potentially hard-to-get hardware.
"Acquiring and setting up the DragonBoard 410c proved to be a significant hurdle and added unexpected cost."
"The course heavily relies on a specific development board, which might be costly or hard to find in some regions."
"I spent a considerable amount of time troubleshooting the DragonBoard setup before I could even start with the projects."
