HACK 32 - Make Calls with a Raspberry Pi Asterisk Telephone System
Asterisk is a telephone system in software. It is typically used to bridge callers together, or offer up features such as voicemail or call queues. Because it’s built totally in software, you can run it on your Raspberry Pi.
Because the Raspberry Pi doesn’t have any sort of analog telephone connections, setting up Asterisk means using a technology called voice over IP (VoIP) to communicate on the Raspberry Pi. You’ll use a computer program called a softphone, together with a microphone and speakers, to emulate a telephone. The softphone will then communicate across the network to Asterisk running on the Raspberry Pi.
Niets gaat vanzelf:
This hack uses a VoIP protocol called SIP to communicate between one or more softphones and Asterisk. Getting SIP working through a firewall (especially a NAT firewall) is difficult and beyond the scope of this hack. In order for your connections to work, you’ll need to turn off the firewall, so that it doesn’t block connection attempts.
----------------------------------------------------------------------- Don’t leave your Raspberry Pi connected to the Internet with the firewall disabled, because someone will likely attempt to try to break into your Raspberry Pi. This is especially important if you haven’t changed the password on your Raspberry Pi from the defaults. We suggest you turn off the firewall on your Raspberry Pi only long enough to test out things, and then turn it back on. -----------------------------------------------------------------------

Lente en telefoniesystemen, dan weet je het wel, Peer-to-Peer SIP:
Er worden hormonen en neurotransmitters (oa. fenylethylamine, noradrenaline, adrenaline, endorfine, dopamine en oxytocine) in de hersenen aangemaakt. De hormonen die vrijkomen zijn verslavend.
Kenmerken:
- lichamelijke gevoelens vertonen als ‘weke knieën’
- gebrek aan eetlust hebben
- aan lichte slapeloosheid lijden
- zwetende handen hebben
Maar zover zit het er ook niet naast, begon destijds met telefonie en iedereen zit daar nog steeds:
Many Own Cell Phones, Few Have Landlines
To access the internet, people increasingly use smartphones rather than more cumbersome fixed landline connections and computers. For those in many developing countries, a smartphone is their first computer and their only Internet-connected device. Around the world, both smartphones and basic-feature phones alike are used for sending messages and taking pictures.
Waar de ‘landlines’ altijd al wel lagen heeft ‘copper’ nog steeds de overhand:
