Residential VoIP

VoIP Tech Chat posted a new article discussing residential VoIP (and the savings you can get from switching). It’s an interesting read, especially the data with wireless only usage and some of the savings breakdown.

For a typical household, VoIP remains a very cost-effective telephone solution; although you must remember that without good (and we mean good), high-speed Internet, your VoIP will be unusable. Many local phone companies offer a “dial tone only” line for less than $15.00 monthly. With the use of VoIP and a dial-tone only landline, you can still save more than $150.00 yearly while providing your family a reliable method of calling during emergencies and power outages.

Asterisk Security Advisory AST-2009-002

Digium announced today a Remote Crash Vulnerability in the SIP Channel Driver affecting recent versions of Asterisk 1.4 and 1.6 branches. The full Advisory can be read directly from the Asterisk Project Security Advisory:

Description: When configured with pedantic=yes the SIP channel driver performs extra request URI checking on an INVITE received as a result of a SIP spiral. As part of this extra checking the headers from the outgoing SIP INVITE sent and the received SIP INVITE are compared. The code incorrectly assumes that the string for each header passed in will be non-NULL in all cases. This is incorrect because if no headers are present the value passed in will be NULL.

The values passed into the code are now checked to be non-NULL before being compared.

Resolution: Upgrade to revision 174082 of the 1.4 branch, 174085 of the 1.6.0 branch, 174086 of the 1.6.1 branch, or one of the releases noted below.

The pedantic option in the SIP channel driver can also be turned off to prevent this issue from occurring.

Affected Versions

1.4.x (Versions 1.4.22, 1.4.23,
1.6.0.x (All versions prior to
1.6.1.x (All versions prior to
C.x.x (Only version C.2.3)

The Asterisk S-Prize

John Todd, with Digium, announced a very cool contest — The Asterisk S-Prize.

To encourage the improvement and testing of larger-scale Asterisk systems, I’d like to repeat here what I mentioned today on the asterisk-dev mailing list: I’m putting out a semi-official challenge in place. The first person to get an Asterisk system moving 10,000 G.711 call legs through a single instance on a single machine will get a first-class steak dinner at Astricon. And a great bottle of wine, if that is your preference.

To read more about the contest, check out the official post at Digium.

Asterisk Security Advisory

Digium, the makers of Asterisk, announced today a new release of the Asterisk Telephony Software. The updated software contains a security release affecting all previously released versions of the software. It is recommended that you make sure you have upgraded to the most current version of this software; available for free from Digium.

These updates are a fix to a previous security release (released as versions 1.2.31,, and

The new versions are being released after additional testing revealed some issues with the way that scanning for users was blocked. Those issues have been corrected in this release.

This security issue affects the 1.2, 1.4, and 1.6 series of Asterisk.

Also note, that Asterisk was released yesterday prior to the security update. That release has been removed as there will be no release, but rather will be reincarnated as The reason for the dead release is to avoid 5 digit release numbers.

Parking Availability, Team Forrest, and Asterisk

Ann Arbor Parking

Recently, Fred Posner of Team Forrest, assisted Edward Vielmetti with a simple idea — help make information accessible. In this case, the information was the availability of Parking Spots in Ann Arbor, Michigan.

The Ann Arbor Downtown Development Authority (A2DDA) publishes data regarding parking spot availability on the web, however, when you’re driving to the garage navigating to a web site is the least of your worries. So, an idea was born to make parking information readily accessible — and with that, Team Forrest’s Fred Posner built a quick prototype to demonstrate how Asterisk (by Digium) can help rethink how data can be accessed.

In the prototype, a caller can select which garage to query. The system will then speak to the caller the remaining number of spaces and offer 3 options — select another garage, exit (and hear the local weather), or choose to be notified if there are fewer than 10 spaces remaining. If the caller selects the notification option, the system will automatically check once a minute (for 30 minutes) and initiate a call out to the user. The call will remind the user which garage they selected and inform them of the current number of available spaces.

The prototype for this project can be accessed from the Team Forrest main line, at +1 (212) 937-7844. Then, choose 6 for check local Ann Arbor Parking availability.
