SIP

tl;dr: New venue, amazing people, well run, good food, great content. Looking forward to 2025. Got back recently from my trip to Berlin and absolutely loved this year’s Kamailio World. The 2 day event covered a variety of Kamailio/VoIP related talks, as well as some talks dealing with 5g, 6g, and even communicating in Space. New Venue Kamailio World took place at Novotel Berlin Am Tiergarten – steps away from a train station, the Charlottenburger Tor (big gate), and a short walk from the Victory Column....

We have a new go(lang) based APIBAN client that will send IP addresses directly to your chosen fail2ban jail. The new client comes to us from concerns of FreePBX users of fail2ban fighting iptables additions. There’s other benefits for freepbx users, including seeing IP addresses in the GUI, etc. There’s also a super simple, lazy install method: curl -sSL https://raw.githubusercontent.com/apiban/apiban-fail2ban/main/install.sh | bash -s -- APIBANKEY (where APIKEY is your APIBAN API KEY)...

Next stop, Berlin! In just 2 weeks, Kamailio World 2024 will be held in-person and in Berlin. This year, there’s location and I’m excited to both attend and speak. If you haven’t gotten tickets, there’s still time to register. My talk is titled HTABLE vs REDIS: Is There A Performance Benefit? and is set for April 18th. Looking forward to seeing many of you (and hopefully meeting more people from the community as well)....

Well, so much for that. After trying poison for a while, I just didn’t like it. I did love the mermaid diagrams though… Oh well. I went back to an oldie but a goodie… papermod. Clean, simple, dark mode. The only thing it was missing was those damn mermaid diagrams. Of course, that was easy enough to add.

Another day, another template… this time I’m trying out poison. One of the neat things with this template is the incorporation of Mermaid diagrams sequenceDiagram participant Alice participant Kamailio participant Bob Alice->>Kamailio: INVITE Kamailio->>Alice: 100 Trying Kamailio->>Bob: INVITE Bob->>Kamailio: 180 Ringing Kamailio->>Alice: 180 Ringing Bob->>Kamailio: 200 OK Kamailio->>Alice: 200 OK Alice->>Kamailio: ACK Kamailio->>Bob: ACK Alice->>Kamailio: BYE Kamailio->>Bob: BYE Bob->>Kamailio: 200 OK Kamailio->>Alice: 200 OK Seems like a pretty awesome feature for someone who blogs a bit about SIP, no?...

Kamailio World remains one of my favorite events of the year. I am very excited that Kamailio World will again be held in-person and in Berlin. I’ve gotten the tickets… I’ve made my reservations at the new venue… and I am ready to see Kamailians from across the globe as we discuss all things Kamailio. If you’ve never been, you can see some past events on the Kamailio World YouTube Channel....

You’ve probably heard me say (once or twice)… 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/APIBAN. I started APIBAN back in 2020 and for the past 3 years have greatly enjoyed helping others protect their SIP systems from IP addresses sending unwanted traffic. The service is provided for FREE....

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....
