I finally was able to contact my dentist. They use a weird system where there is only one way to contact them; A phone line that ring 4 time, available 10h-12h, and if no one answer it just hang up automatically. No mail or other way to contact them. And no one ever answer.
So I set up an Asterisk-FreePBX server with my number at voip ms and made the system ring them none stop and connect me via my cellphone upon success
Took them ~1.5 hours to respond... The women was pissed ^^' (372 calls)
@Sabex It's easy to get it; it's a fiscal problem.
They want to pay 6 figures salaries (to theirs doctors and the minimum wages to others...) and pay little to no taxes. They need to stay in the "company size" where the government allow such things.
It's way more complex than that.. but it's the concept.
