Recently, I posted about using Kamailio’s PIKE module to help block excessive SIP traffic. This is a great tool for helping your system handle high traffic SIP, such as floods. But, what can you do when someone sends garbage or non-SIP traffic to your system? Kamailio’s SIP parser is handled in the core and was recently upgraded in v5.5 with logging improvements, as well as simplified implementation, static map for header name, and type for parsing....
The Pike module in Kamailio provides detection and alerting of “excessive” SIP traffic to your system. Within the module you can configure the rate limit, time period, and amount of time that the IP (ipv4 or ipv6) should be blocked. For example, you can configure your system to say that 30 requests from the same IP within 5 seconds should trigger a block of that IP for 5 minutes. I absolutely love this module and, in my case, Pike more often finds abusive traffic (like dialers) than SIP floods attacks....
Well, 2020 is certainly a strange year… Some of us have been working from home for a very long time while others are now just understanding the benefits. Of course, when a drastic change in work environment becomes a forced change, the implementation can be quite daunting. Let’s look at telephony for example. Many small, medium, and even enterprise PBX deployments have been designed to only allow endpoints (aka phones) to connect from within the local network....
From February 11th through 15th, 2020, Open Source World (or open source summit?) will be colocated at ITEXPO 2020 in beautiful Fort Lauderdale, Florida. This year, I will be speaking the gospel of Kamailio with a presentation entitled, “Using Kamailio to Secure Your Communications” (currently scheduled for February 13th at 3pm). What previously had been Asterisk World has been replaced with Open Source World… and has attracted an incredible array of speakers from the open source RTC community; including Dan Jenkins, Lorenzo Mangani, Anthony Minessale, Nir Simionovich, Jared Smith, James Body, David Duffett, Allison Smith, Eric Klein, and more!...
Did you catch Fred Posner on FLOSS Weekly discussing Kamailio?Fred discusses Kamailio on FLOSS Weekly FLOSS all about Free Libre Open Source Software. Hosted by Randal Schwartz and his rotating panel of co-hosts every Wednesday as they talk with the most interesting and important people in the Open Source and Free Software community. Fred was honored to discuss Kamailio with this group and would join them again in a heartbeat.
It’s summer-time, very hot, very humid, and this means… it’s time for ClueCon! I’m losing track, but this year will be my fourth or fifth time attending this conference in “beautiful” Chicago. ClueCon is a conference for developers by developers: an annual technology conference held every summer hosted by the team behind the FreeSWITCH open-source project. ...
Just returned from an incredible trip to Berlin for Kamailio World 2018, the 6th annual meeting of all things Kamailio. As expected, I had a wonderful time meeting new Kamailians from across the globe as well as catching up with friends from years past. I was honored to present at Kamailio World regarding Open Source Software Myths and combatting FUD. Thanks to Pascom, you can catch my presentation on YouTube:
In just a couple weeks, the Mrs. and I will be headed back to Berlin for Kamailio World. Last year, we visited for the first time and Berlin truly made an amazing impression. Yeni and I have always shared different views on punctuality, so visiting a city where timeliness actually means something had me in a great mood. Food was great, pricing was amazing, and transportation was easy. Fred and Yeni in Berlin To gear up for the trip last year, we upgraded our credit card to a card with no foreign transaction fees; and then found most places we visited in the city (as well as Germany as a whole) preferred cash....
It’s not too late to make plans to visit Berlin this May and join us at Kamailio World 2018. Kamailio World allows Kamailians, VoIP enthusiasts, and more to Connect, Inspire, and Create during an amazing conference. Last year, Yeni and I flew out for the first time and I only regretted not attending before. I am lucky (and honored) to attend many VoIP conferences throughout the year and Kamailio World is on my must attend list for a simple reason— the ability to connect with this amazing community will inspire you to create something amazing. ...
TL/DR; — Even older, even fatter, longer goatee. Last year, Yeni and I crossed some items off her bucket list; most importantly visiting Castle Neuschwanstein and making it to Europe. I was able to attend a Kamailio World which exceeded all of by greatest expectations (I’ve already blocked out 2018). ...
