It was not my intent to come across this way. To be honest, the project I'm working on isn't even completely fleshed out, and I too am slightly 'in the dark' on details. I was simply doing some preemptive investigative work into the software side of things.

Your position is understood, but incorrect in this case.

Sounds like a security monitoring package (minus the video) should do the job? Thanks for the info, I will have a look at those. A little Googleing shows up these. http://oreka.sourceforge.net/about/ http://www.ubuntugeek.com/how-to-recording-internal-audio-in-ubuntu.html What else do you want it to do? No idea at this point.

Re: [asterisk-users] Asterisk - Soundcard - Recording?
- Original Message - I'll take a stab, since you said no GUI and also USB based mic. Raspberry Pi project? I'm interested in this vein as well, Nope, the RPi is not a component. BUT, a good suggestion for a small board. I'll keep it in mind. especially after the recent post about voice recognition. I was thinking that Raspberry Pi's with mics could live around my house and all have dedicated always-open channels to a conference bridge in the main asterisk box. I was planning on using ALSA and a USB mic on a local Raspberry Pi asterisk instance. Very interesting. You could use the CONSOLE for the audio device and at the same time get the ability to make/take calls via Asterisk CLI or .call files. So given that we know basically what you are trying to do, the original question was OSS versus ALSA for USB mic, correct? Has anyone had any thoughts on that? I thought ALSA was built in to the kernel and OSS required some hacks. But that is a pretty fuzzy recollection. I think it depends on the kernel being used. Research is needed, but IIRC, you are correct, ALSA is included or at least fully supported whereas other sound systems are 'less than stellar'. --Tim -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
