Once I dropped a new iPhone 5s from a knee-height onto a tile, the phone was in a protective bumper, as soon as I lifted it, I noticed that the flashlight button was not active. I rebooted it, the button became active and the flashlight worked, at that moment I even shot a video, but the next day when the camera was turned on, a black screen was displayed when the camera was turned on.
For some time, I managed to switch to the front camera, but the rear one did not work.
Sometimes you could see the warning “Flash is Disabled – The iPhone needs to cool down before you can use the flash.”, But the phone was not used before and naturally could not overheat.
Sometimes also after a couple of reboots, the rear camera could start working and then again there was a black screen.

I will give an example of setting up SIP Trunk in Asterisk, that is, Asterisk will be in the role of a SIP client.
From the provider Ukrtelecom received data: number, password and address of the telephony server (sip.ukrtel.net).
SIP number was taken to make multi-channel not an ordinary city number, by forwarding in case of busy lines.
I will configure on a Linux server with a real IP without using NAT, as well as on another with NAT (in the second case, you need to change nat=no to nat=yes and comment out canreinvite).
