Recently, I participated in a discussion about using Asterisk on the Raspberry Pi, to provide a call filtering facility for a home installation. My correspondant had tried to set up a Raspberry Pi and VoIP handset to handle phone calls such that incoming calls would pass through a whitelist/blacklist, promoting good callers and damning bad callers, while directing outgoing calls to their intended destinations.
In the year and a half since I wrote IP04 Progress, I've expanded my simple telephone system into something a little more comprehensive. I had three goals in mind; to provide that "complete accounting" of incoming and outgoing calls that my provider wouldn't supply, to manage the incoming calls so that I would be less bothered by telemarketers and other annoying callers, and to position the IP04 as a part of a much larger home automation project.
I've slowly worked my way towards all that, in fits and starts, and am ready to share some of my progress.
Since I wrote my "IP04 and Me" blog post, I've made remarkable progress. My home phones now run completely under the control of the IP04, and I have that virtual receptionist I've been working towards.
For years, I've played with my 4-port embedded-linux Asterisk PBX (the IP04 from rowetel.com). Now, I've finally decided to move it out of the toychest and into real use.
For a long while, I had put aside my IP04 to concentrate on other things. Recently, I resumed my explorations of the IP04 device, still with the long-term notion of using it as a home PBX.
I'm glad for the extended absence; it allowed me to reconsider my approach, and (when I resumed playing with the IP04) do some things that I had previously found impossible to do.
