Asterisk 101 – Ghetto GoogleVoice : Signing up for / using GV even if you’re not in the USA using Asterisk

GoogleVoice (GV for short) is a great service (I won’t go into the details, but you can read up about it here), but it is unfortunately accessible only if you are in the USA.
Granted there is already plenty of documentation about how to circumvent this, but I’m not aware of any of those using Asterisk.

So this post will document how to sign up for a GV account as well as how to use it with Asterisk afterwards, in the prospect of using it if you are not in the USA.

In order to be able to sign up for GV, you need to meet 2 prerequisites :

  1. You need to have a US IP address
  2. You need to have a US phone number, which will be used to validate your GV account

Step 1 is left as an exercise to the reader (“Good luck ! I’m behind 7 proxies !” :D).

Step 2 is the one we’re going to describe here, as an example of what you can pull with simple Asterisk configurations.

Unix 101 : Showing non-printing characters in text files (ex : DOS files)

A non-printing character is a character which won’t actually get directly printed (or displayed) but rather interpreted. Such non-printing characters are for example line-feed or tabulation. The interpretation of those characters can differ from one system to the next. For example the line-feed character is different on Unix or DOS.

If you need an easy way to confirm that a text file is DOS or UNIX formatted (they differ with respect to the end of line character(s) for example) or if you wish to display normally non-printing characters of a text file, you can use the -vET command line switches of the cat utility.

As explained in the man page :

  • -v : will use the ^ and M- notation for control and multibytes characters
  • -E : will make ends of lines visible
  • -T : will make tabulations visible

For example : Continue reading Unix 101 : Showing non-printing characters in text files (ex : DOS files)

If like me you get tons of telemarketers calls, there’s an easy way to get rid of them with a quick Asterisk hack. The following Asterisk configuration snippet will immediately send any hidden caller ID (99% telemarketers, and I have a general policy of not picking up the phone for hidden caller ID anyway) to a holding music making them waste money and time…
