[Freeswitch-users] Dial String Inject in FreeSwitch

Mon Feb 22 09:26:00 PST 2010

Eder,

If you fear people can do such *really stupid* things, and this is
nice from you, please add something to the wiki, for example a
paragraph in the dialplan page, or whatever, explaining why this is a
stupid thing.

If you publish a page in your blog, that look like a security alert,
or that you found a security flaw in FS, people will rightly think
that you are just looking for some attention in the search engines,
and to bring viewers to your page.

Also, in doing so, you push non technical people to think there is a
security problem in FS, and this is really a big damage to the
project. Because it is not true, it is just how it look like in your
page.

So, delete that page, and add something to the wiki, if you care about
telling people not to do stupid things.

But please, be aware that your page, the page you published, is really
something that do a damage and put a bad light on a project, and there
is no one reason for doing this.
