Kamailio, VoIP, Rants, and more.

Kamailio World 2024: Thoughts

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....

APIBAN now integrates with fail2ban

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 | bash -s -- APIBANKEY (where APIKEY is your APIBAN API KEY)...

I tried to buy an iPhone

It’s been a long time since I bought my first Mac and got an iPhone not much later. I like Apple for the most part. Spent a few years with just a linux laptop/desktop, but got a M2 Macbook Air last year and, well… I say all that to say this: For the most part, I’m pretty happy with Apple. Products are good, usable, etc. Don’t have many problems. Because of this, and since it’s been a few years since the Mrs and I have upgraded the phone, I decided to get her one of those new iPhone 15 Pros....

New (Old) Look for the Blog

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.

New Look for the Blog

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?...

Astricon 2024/ITEXPO

I won’t be attending Astricon this year. Once again, Astricon has co-located with ITEXPO in beautiful Fort Lauderdale, similar to the old Asterisk World events (that Sangoma ended soon after acquiring Digium). Astricon, in past years, attracted an audience of more than 1000 attendees, a decent sized expo (focused on open source telephony), and multiple presentation tracks held over several days. This year, similar to last year’s Astricon, the conference will be a single track and (new for 2024) only one day long....

APIBAN Now with HTTP Honeypot Data

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....
