Friends,

Last week, Hans Petter Selansky alerted us of a potential security issue in all releases of Asterisk. In fact, it doesn't involve the code, but the most common way to construct dialplans. If you have something like this in your Asterisk, you need to update your dialplans:

[incoming-from-voip]
exten => _X., 1, dial(SIP/${EXTEN})

Many VoIP protocols support a large character set, that may cause harm in your dialplan

Hello Asterisk Users and those with an Interest in VoIP Technology,

The agenda for our March meeting is: VOIP Basics at the Twin Cities Maker location. I'll bring a simple computer with Asterisk running with a few extensions. I'll probably cover a little of the history of Asterisk and have a few other things for "show and tell". I'll bring a few copies of the latest CD for PBX in a Flash for people that want to try it on their own equipment.

You can see our calendar entry on March 13th. http://www.tcmaker.org/blog/calendar/
