Wow shocked
A truckload of resources to consume!

Still struggling with understanding all the basics of PBX as explained in the part 1 of that series.
But I managed to to the PBX VM on Virtualbox today.
Hopefully, will make more progress tomorrow.

Are you into embedded systems as well? I mean I2C, SPI, RTOS and those bare metal stuffs?


Lol! Truckload I know. Bookmark them. Come to them later. I may not be readily available soon. So I'm "dumping" as much as I can until my next relatively down time which may be for a few months. Focus on the Videos for now. All 32. After that we'll see where I can point you. Don't forget to keep your C/C++ in view. Very important. VERY IMPORTANT. Not all "seniors" have malicious intentions lol. (I'm not a senior o. Cos where you feel say you sabi reach you go see who sabi )

My fun projects are more towards home labbing. Currently messing about with home and building automation. Hard to do it properly in Naija because the electrical wiring in our homes are worse than substandard. But we still dey try to get around it

Handful of Raspberry Pi projects as well.

Here is an interview process for a Senior VoIP Engineer on indeed with Diabolocom
Recruitment Process:

1. Technical test.
2. Call with Talent Acquisition Manager.
3. Tech interview with VoIP team.
4. Interview with CTO.
5. On-site interview with the team

Haba! Is this not too much

I don't know if this is a standard process for hiring Senior VoIP Engineers. I've not had more than one round of screening before getting an offer.

I understand the need though for a "Technical Test" even though no one really does a "Technical test" unless for the really really big voice providers like possible Sinch or maybe RingCentral or 8x8. You work your way through the ranks (or at least that's what I've done). My CTO regularly got on troubleshooting calls when things got red. At the heart of it though is a very good knowledge of SIP. The "holy grail" for understanding SIP is the book "SIP: Understanding the Session Initiation Protocol" by Alan B Johnston. If you know it like the back of your hand you will destroy most interviews. I say most because some of our work is also a people-management job. Customers regularly lie about what they have or haven't done to their physical phones or their network. You need to be able to dance around those with deft people skill.

A technical discussion is enough to know if a candidate can do a tech job. In most cases a technical test is just used to make candidates to do the company's work for free.

For this kind of drawn out screening, there's no way anyone is going to accept anything less than $180/hr. Most likely $200+ hourly. It's unnecessarily drawn out for an experienced Senior. Most seniors know the technical in so much depth that a Technical "test" will be very condescending.

Edit: I just looked at Diabolocom and see that it's a European (French) company. EU pays considerably less than North America, so offer may be significantly lower than what I quoted above in USD.

Use media stream record and save the files of each students in Amazon s3 storages or Azure or wasabi or Google cloud to server. If you use Voip it is like initiating a call when the examination is going on and when the call ends you will store the records on cloud storage.

First thing that came to my head is SIP over WebRTC. Two use cases I see would for 1) monitoring sound from the examinees location and 2) two-way communication between the examinees and the invigilator.

Not something I've ever done but I can see why it could be needed. Is it the best option for just invigilation? It may be overkill I think. Something like a WebRTC with recording software (Oreka/Orecx) would be my preferred rather than heavyweight VoIP like Asterisk or Freeswitch.

Checkout Janus or Livekit for open source stuff that I think should be able to better handle it

Soooo, I just read one guys post on a different platform and had to come back here quick quick.

I imagine there are people who will see this as show off, bragging or being proud. Abeg o, if that is how it has come across to anyone here, I apologise. It's very very far from bragging. How much I get wey I go dey brag or dey form?

It's more about me trying to give back. To spark something in someone. Anyone really. We really don't need to japa to have a chance of success in this IT "runs" wey we dey do. Yorùbá say ona kan o w'oja (many roads lead to the market). I'm just trying to shed light on one of the least travelled ones. Who knows maybe someone may decide to enter it.

Una doh o. I greet all of una

PS: I go drop the professional tone and try to be more approachable. Na work mode dey let person type with one kind "forming" language. I be full Waff boy forget all the big big grammar

Hello man,
The FreePBX dashboard is now behind an IPv6 link-local in Virtualbox (interface:eth0, IP:fe80::d6cd:34b:33f8:44cf)
My research so far says browsers do not link-local requests.
SSH forwarding to redirect localhost calls from my Windows?
How to setup such?

Are you installing FreePBX 17? You'd need to install Debian 12 first before running the script to install FreePBX on top of it. If that's going to confuse you, just the most recent version of FreePBX 16 (hxxps://s[.]freepbxdistro[.]org/ISO/SNG7-PBX16-64bit-2306-1[.]iso) and follow the guide above
