Alex Balashov Discusses High Performance Kamailio Tuning

I’ve discussed why I love Kamailio many times on this site — and the Kamailio community remains a strong reason for my love of the project.

Alex Balashov, a VoIP Engineer and member of the Kamailio project, is a VoIP expert and his knowledge of Kamailio, SIP, and telecommunication is without question. He also happens to be the fastest typist I’ve ever seen (seriously, it’s almost distracting).

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. =)

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.

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.

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 https://github.com/kamailio/kamailio.git
  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:

Rant

Your Phone Company is Watching

Back in 2012 or so, I posted a video hidden within a rant I had made. I rant from time to time. Scratch that. I rant a lot. I blog my rants from time to time.

Anyway, I think about this video often.

Malte Spitz asked his telephone company what type of data they had been collecting on him. An innocent question… what type of information are you collecting?

The results astounded him and he effectively communicated why we should all be concerned.

For those of you out there who don’t find any significance to the Snowden releases, the information our NSA collects, and why blanket collection of data is a dangerous tool… I ask you to watch the movie.

It’s a quick 10 minutes. If you’ve seen it before, it’s time to watch it again.

Malte Spitz asked his cell phone carrier what it knew about him–and mapped what he found out.

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.

Literally.

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
