In just a few weeks, I’ll be headed to ClueCon2023 in Chicago. I generally enjoy going to ClueCon and am happy to say I have lost track of the number I’ve attended. This year, I’ll be giving a talk called Kamailio with FreeSWITCH B2BUA: Sometimes, you just want a B2BUA that’s not touching media. FreeSWITCH does this very well and with Kamailio and RTPengine you have a very scalable, high performant B2BUA SBC....
I love Kamailio World and cannot properly describe how excited I am to return to Berlin for an in person Kamailio World. I am honored to be presenting in this year’s schedule. My talk, Using APIBan In Productions, will be at 1100 on June 06, 2023. It’s been a few years since we last visited Fraunhofer Forum in Berlin to gather for the conference and I’m very excited to see old friends and meet new people....
Kamailio v5.7.0 is out – a new major release, bringing new features and improvements added during almost twelve months of combined development and testing. It’s always exciting when a new, major Kamailio release launches and I’m sure this release will be talked about during Kamailio World (coming up in just 2 weeks!). Some highlights of this new release: 4 brand new modules (including tls_wolfssl) topos option to mask call-id options for loading modules support for long values instead of int for variables new variables and transformations For more information check out https://www....
We recently made some dramatic enhancements to the APIBAN infrastructure. As I joked on Mastodon, I must be getting older as these improvements were made well before an emergency. If you’re not familiar, APIBAN helps prevent unwanted SIP traffic by identifying addresses of known bad actors before they attack your system. Bad actors are collected through globally deployed honeypots and curated by LOD. You can access this data via API or automatically block the traffic with our open source client....

These do not necessarily represent the views and opinions of any company or project that I am (or have been) associated with. Back in 2019 (around 3.5 years from this post), I blogged that Sangoma Doesn’t Get Open Source. The post generated a decent amount of discussion and later that year, Dan Jenkins and I sat with Bill Wignall and made commitments about future conferences, handling “open source,” and stopping FUD....
The wonders of troubleshooting SIP never cease. Ever try to open a pcap with sngrep only to get the following error? Couldn't open pcap file XYZ.pcap: unknown file format And then, even though you hate looking at SIP on wireshark, you are left wondering… Why does this file open in Wireshark, but not in sngrep? Well, most of the time, this is because the pcap file is actually compressed. Easy fix....
Well, ITEXPO 2022 has come and gone. I think there were perhaps 2-3 other people at the conference who wore a mask. This said, I did return home without covid… The presentation was interrupted by a fire alarm. Apparently some idiot decided it would be fun to smoke in the bathroom. Wasn’t cool in the 80s, still isn’t cool today. Anyway… Unfortunately, coordination was very lacking at the event and no information regarding extending time made it to any of the presenters/attendees in our room....
Sangoma recently announced that Astricon 2023 will be co-located with ITEXPO in Fort Lauderdale. Here’s their exact announcement: With tremendous excitement, we officially announce the return of an in-person AstriCon. We will ease into the in-person event by co-locating AstriCon at ITEXPO on February 13-17, 2023, in beautiful Fort Lauderdale, Florida. The longest-running open source convention, AstriCon, celebrates open source projects featuring Asterisk and FreePBX. The event will include two tracks, sessions, and an EXPO hall....

Generally, when I deploy Kamailio, I use git. Many reasons for this (including being able to quickly apply a patch or fix), but that’s a discussion for another time. If you’ve installed from git and need to add a new module (that hasn’t already been built/installed), the process is very straight forward (and simple). Step 1: Install Dependencies Some modules require libraries to be installed. For example, the jansson module wants the jansson library to be installed....
