Loved it, it's amazing. Few questions How many developers developed it? How much time it took? You started earning? How are you advertising? Why not people call from there phone for international call?

How many developers developed it? Just myself, I hardly slept enough during building it, but it paid off :D

How much time it took? I started in April, but started coding enf of May

You started earning? Yes, 2 paying customers, very very minimal but that prooves the need I think

How are you advertising? Hard, still trying to market to it

Why not people call from there phone for international call? It's expensive; this is a cheaper option for sure.

Ask me anything related to the technology/revenue and whatnot...

Extraordinary! Congratulations. I’ve always been fascinated by the world of telephony. How did you manage to get numbers for every country? Do you have direct access to SS7, are you a virtual operator, or do you use third-party services for each country?

Usually, you need a presence in each country, like an official entity. It's easy for a myriad of countries to do that for a fee; even in Dubai, you can form a company. Then you can acquire numbers easily in these countries. I am now supporting the UK (easy to get)/US/CA, and will soon support some European countries as well. What's hard are the countries that require authority talks like Egypt :D

I am Egyptian living in Europe, so I want to support it, but I left it for a bit.

There are a lot of telephony providers out there (Twilio, Bandwidth, etc.) So it's easy to start building.

Do scammers still try to get "local-seeming" numbers? Any mechanisms to prevent them registering, using stolen credit card numbers?

I have monitoring in place for such behaviour, also detection for too many calls under specific amount of time with locations. I am still very new to actually have scamers finding the website I think.

Scammers have ways to spoof numbers. I doubt they will bother buying numbers unless they can get a bunch of them.

On the first page, there's the claim:

  Encrypted Calls
  
  All calls are encrypted with TLS 1.2+ for signaling and SRTP with AES-128 for audio. Your conversations stay private during transmission.
This can only be true on your (Voklit) end between the client and the server, it stops being encrypted both from signalling and audio perspective the moment it hits the PSTN in any country on any network.

I would consider re-phrasing this so that limitation is more clear, for people who may misinterpret that encryption claim, unless you've found a way to encrypt PSTN signalling and audio which would be a much more impressive feat.
