For some reason, I started believing that good quality headphones were worth a hefty price. The problem? Good quality headphones do not exist. Take for example Bose.

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!).| Fred Posner

I love git. Love it. I’ll save my love for Gitea for another day (TL;DR: Gitea is awesome). Anyway, a lot of git repositories allow you to use ssh keys as authentication.

Last Thanksgiving, thanks to Covid, Thanksgiving was quieter than normal.

The major announcement at ClueCon 2021 was the release of FreeSWITCH 1.10.7.

After spending many years on Wordpress, I’ve decided to make a change in the software running this site. First of all, I have absolutely nothing against wordpress. I’ve used wordpress for well over 15 years at this point.

You can literally get started in 5 minutes.| Fred Posner

Twenty years ago, I started The Palner Group, Inc. with the goal of providing technology consulting as a service. 2000 feels like a century ago (I’ve not thought about the millennium bug for some time now) and I’m using this anniversary to reflect on having this company for two decades.| Fred Posner

Had a great time visiting with members of the open source VoIP community in Fort Lauderdale for open source world / itexpo 2020.

In 1990, while a freshman at UF (Go Gators!), I applied for and received my first credit card. The card, from Citibank, was a “college special” with a whopping credit limit of $600.00 and fees/penalties as high as the Federal Government would allow. This said, there was no yearly fee and I knew at the ripe age of 18 that if I paid my balance on time, my cost was 0.00. Granted, I didn’t have much money (like generally a bank account of 200.00 or so) and got the card in case I needed food...| Fred Posner
From February 11th through 15th, 2020, Open Source World (or open source summit?) will be colocated at ITEXPO 2020 in beautiful Fort Lauderdale, Florida.

I’m not a programmer. Never tried to pass myself off as one — which made for a really, really awkward interview once… but that’s another story.

TL;DRA few weeks ago, I had some strong concerns over Sangoma’s stewardship of Asterisk and FreePBX. Since that post, Astricon showed that Sangoma definitely appreciates the open source VoIP community and I’m optimistic for the future.
