Last Friday, I held a workshop session titled “Omnichannel Voice AI Systems Architecture” at DevFest Abuja 2026 @gdgabuja.
I started by inviting two audience members to make a live call, one over PSTN and one over WhatsApp, and the voice AI agent picked up and held a conversation with each on the spot. I loved the energy in the room.
From there, I walked through the applications of voice AI and the technologies that power it, such as WebRTC, Session Initiation Protocol (SIP), Public Switched Telephone Network (PSTN), Selective Forwarding Unit (SFU), Multipoint Control Unit (MCU), large language models (LLMs), Speech to Text (STT) models, Text to Speech (TTS) models, and Speech to Speech models. The STT transcribed Nigerian speech accurately, and the TTS spoke back to callers in a Nigerian accent.
I also broke down how the audio actually moves from the moment a call is placed, how the carrier delivers the call as RTP, how the SIP bridge converts it into WebRTC, and how the agent then streams it bidirectionally over WebSockets to the STT and TTS services before the reply goes back to the callers.
Overall, I had a great time showing the audience how a voice AI agent is put together across multiple channels. A big thank you to @gdgabuja, the organizers for the opportunity. Looking forward to doing more of this.

We just crossed over 1,000 orders in a single day in Ghana - in under 3 months! 🎉
It took us 11 months to hit this in Nigeria, and we are excited at how fast the growth has been since we launched in Ghana.
The @chowdeck Nigeria team travelled to Accra to celebrate with the @ChowdeckGH team and share the joy of this milestone. To everyone who has been part of this incredible feat, a big thank you 🙏🏾
It’s still day 0 on this journey and we are blazing on with anticipation and energy! 🚀
I was going to hold off on coming back to this but well here we go. The day I made this post I had just gotten my last paycheck from a company I was working for that shut down. I was in a dark place.
@bigbrutha_ Movie files are in GBs/TBs. So they convert files to codecs(h.264, vp9), and resolutions. Save that to s3, and their CDN. When you watch a movie, they stream a codec compatible with your device, from the closest CDN to you, using ABS streaming. Then you stream in KBs very fast.
Woke up that Saturday and made sure I went to chapel to pray specifically for one thing that day.
“Oh lord, give us this day, victory over our enemies.”
Deep Into the night, winslow hall was rocking when di Maria hit that chip, worse so when the ref called the final whistle.
I sunk to my knees in tears after wild celebrations, God is great, The curse is lifted, Leo Messi is champion of America.
You can never understand what it meant.
