Expanding Asterisk with Kamailio

I was honored to have been chosen as a speaker during Astricon 2015. Thanks to the miracle of modern, digital technology you can now see my presentation online from the comfort of your own chair.

Relive the excitement… or watch it for the very first time. =)


Join Me in Fort Lauderdale for Asterisk World

Asterisk World will be held in beautiful Fort Lauderdale, Florida from January 25th — 28th, 2016. I am very honored to be speaking at this event and would love to see you in Fort Lauderdale.


Kamailio Gets New Logo

To paraphrase the song, Feeling Good:

It’s a new dawn
It’s a new day
It’s a new logo
For Kamailio
And I’m feeling good
I’m feeling good

Just in time to ring in the new year, Kamailio has introduced their new logo. Keeping in the nature of an open source project, the logo selection was conducted in the open and was open to users, developers, management, and anyone who wished to participate in the selection.


AstriCon Comes to the Sunshine State

First, some history.

I attended my first AstriCon back in 2008 and somewhere, I still have my Skype for Asterisk button. At the close of the conference Digium asked for comments—I suggested that the convention look at Orlando, Florida.

Back then, I traveled from Michigan (the dating Yeni period), yet I still maintained a strong bias for Florida. I thought (with the exception of Australia/Asia) Florida could provide both a convenient travel point (for both International and domestic travelers) as well as combine the possibility of a family vacation in the Sunshine State.

Seven years later, AstriCon 2015 granted my wish and I attended Astricon2015 in beautiful Orlando, Florida.


FCC Unwanted Call List? Not Yet

Recently, the FCC decided to publish their “informal consumer complaints about unwanted robocalls and telemarketing calls” to the interwebs.

As someone critical of government transparency, I first want to give credit where due. Releasing this information is a great step forward.

Good job!

Now, if you’re using an open source VoIP system (such as Asterisk, FreePBX, FreeSWITCH, Kamailio, etc.) it would be very easy to automatically block these numbers from reaching your phone.


Join me in Orlando for Astricon 2015

Astricon 2015 will be held in Orlando, Florida from October 13-15, 2015. This year, I am honored to be speaking at the yearly Asterisk conference and exhibition.

Besides listening to yours truly discuss the benefits of Expanding Asterisk with Kamailio, you will also be exposed to such experts as Daniel Constantin-Mierla, Leif Madsen, James Body, Tim Panton, and Yeni’s personal favorite Allison Smith.


Kamailio 4.2.3, Update from git

Kamailio 4.2.3 has been released.

Kamailio SIP Server v4.2.3 stable is out – a minor release including fixes in code and documentation since v4.2.2 – configuration file and database compatibility is preserved.

So, if you’re updating from git, the simple way to update is:

  1. cd /usr/local/src/kamailio-4.2/kamailio (or your kamailio directory)
  2. git pull origin
  3. make all
  4. make install
  5. /etc/init.d/kamailio restart

Problems? I had one…

When I ran the git pull origin command, I kept receiving the error fatal: read error: Connection reset by peer.

I switched to the repository on github, and all worked:

  1. cd /usr/local/src/kamailio-4.2/kamailio
  2. git remote set-url origin
  3. git pull origin
  4. make all
  5. make install
  6. /etc/init.d/kamailio restart

You can see your current url by running git remote -v.


Private Conversations should be Private

It’s a crazy concept…

I feel that liberty allows us to communicate free from government interference. Whether this be business, personal, religious, or any other type of communication… our freedom of speech entitles us to freedom from monitoring our speech as well.

With information from Edward Snowden (and now William Binney), we should be very concerned over the level of interference, eavesdropping, and surveillance conducted against all society.

William Binney recently stated that the ultimate goal of the NSA was total population control.

This should concern you an you’ve been warned about this before.


Kamailio World 2014

Sadly, I did not make Berlin this year to attend Kamailio World — something I hope to correct in 2015.

If you, like me, are unable to attend… there are technological tools to lessen our loss:

Why I Love Kamailio

If we haven’t met yet, my name is Fred Posner. By day, I’m a VoIP Engineer and a baker (yes, a baker).

Since I was a kid, I’ve loved telephones — everything about telephones. Dealing with phone companies and carriers started to eat away at that love… but VoIP brought it back.

One of the products I get to work with is Kamailio.Many of you have never heard of this product.

Even more cannot pronounce it.

In a nutshell, Kamailio is an open-source SIP server. Now, if you’re not a techie, or know VoIP, then…

Kamailio is about communication.


The word Kamailio originates from the native Hawaiian language; translating “to converse.” Kamailio is open-source software allowing people (great, huge amounts of people) to communicate.

Now, back to why I love Kamailio
