I stumbled upon PulseCaster while searching through Fedoras repositories, I was intrigued and had to give it a try. By the website this is the description:
“PulseCaster is a simple PulseAudio-based tool for making podcast interviews. It is designed for ease of use and simplicity. The user makes a call with a preferred PulseAudio-compatible Voice-over-IP (VoIP) softphone application such as Ekiga or Twinkle, and then starts PulseCaster to record the conversation to a multimedia file. The resulting file can be published as a podcast or distributed in other ways.”
It works really well for phone interviews or just recording that call you want to remember. I wouldn’t advise recording conversations without the other parties permission. I don’t know what the law is on that, but if you’re using it for its intended purpose (podcasting) then it serves its purpose. I actually used it to record the Asterisk Area Code Lookup Script.
