ZeroPhone: a phone for tinkerers and hackers using a Raspberry Pi
We need a "gnu-phone-coreutils" package for telephony on the command line ...<p>We should be able to do things like:<p><pre><code>  grep steve numbers_file | dialer
  echo "process complete" >> sms -n 303-555-1212 -mms=0
  </code></pre>
... and we need a GSM firewall ... and a SIM card firewall ... and quite a few other basic command line tools to manipulate a mobile phone from the command line ...
