I've come here to chew bubblegum and watch my #KamailioWorld2026 presentation "#APIBAN and #Kamailio "... and I'm all out of bubble gum.

My slides from Kamailio World (#APIBAN and #Kamailio) have been posted to https://pgpx.io/kw2026/

First up at Kamailio World is @miconda #kamailio #kamailioworld

Kamailio World 2026 is streaming live! https://www.youtube.com/live/jLtwnjQ1NNE?si=XiemIimKuorkRXGg #kamailio #kamailioworld

My monthly reminder that you can read what @sandrogauci / @enablesecurity writes or **wish you had**.

Also, SIP ALG is still a bad idea.

Great to see another new sponsor for #Kamailio at open collective! You too can help support the development and administration of Kamailio SIP Server project at https://opencollective.com/kamailio

Time for me to say... "There are those who read what @sandrogauci and @enablesecurity write and those who wish they had."

Also, very honored to have #APIBAN make the newsletter -- in a good way. ;)

Two **Excellent** trainings being listed (one proposed) via Asipto for Kamailio Advanced Training. If you work with Kamailio, this is an excellent opportunity. And with the training offered remotely, there's no excuse. =)

I have a good time at #ClueCon and am honored to be presenting this year.

My talk will be about running #Kamailio and #FreeSWITCH at scale.

Hope to see many of you in Chicago for ClueCon2024... there's still time to register.

Had an absolutely lovely time at @commcon and very grateful for all of the work @danjenkins did to make it such a welcoming, friendly, and enjoyable event.

I love this community.

Great Day 1 here at @commcon San Francisco hacking away (with some @cloudflare API's), meeting with friends, and meeting new people.

Looking forward to talking about #APIBAN tomorrow.

Hello San Francisco. I did not opt for the yoga room on my way out of the airport.

Big thanks to Lorne Gaetz for his help testing apiban-fail2ban on FreePBX 16/17. His feedback has allowed for script improvements and better documentation.

#apiban #freepbx #OpenSource

https://github.com/apiban/apiban-fail2ban

Added a new simple, lazy install script for the apiban-fail2ban client. The script is geared towards freepbx using "asterisk-iptables" as the jail.

https://github.com/apiban/apiban-fail2ban

#freepbx #apiban #voip

Running #freepbx or a web facing system with #fail2ban ?

There’s an apiban client for that ;)

@north @fredposner I’ve done it a couple times re #kamailio and #apiban - it’s a friendly one to one that’s then broadcast a week or two later.

Just finished the bi-weekly #FreeSWITCH open hours/community call.

I like to join when I can and do want to give props to the SignalWire team for reaching out to the community like they do.

Depot Park Fireworks in #gainesville was phenomenal. Traffic control was horrid but the fireworks were worth it. Absolutely phenomenal.

#gainesvilleflorida #gainesvillefl

How batshit crazy is Palo Alto spamming of #SIP servers?

The 198.235.24.0/24 currently has **102** active IP addresses sending unwanted SIP traffic.

Horrible.

Goodbye #ClueCon and goodbye Chicago

Another #ClueCon done. My streak of not winning any raffle maybe will end next year?

My #cluecon raffle loss streak continues... as well as my streak of sitting next to people that win a raffle. Congratulations to @danjenkins I guess. Whatever.

My streak of never winning a raffle at #ClueCon continues...
