What are you running in terms of a kernel or distro? I'm running a Debian Woody with a handmade 2.6.5 (based on a woody backport) Otherwise - without the -p option - the system had values of 400ms (and higher) converting speex when it wasn't idle. Now the value is constantly at about 210. Nice. The system is now giving Asterisk the priority it needs. Don't forget to change that in your rc.local, or wherever you're starting Asterisk from. I'm starting it from a start-stop daemon. AT the moment I'm having a little fight with it. When starting from the script it tells me "Starting Asterisk PBX: Unable to set high priority". Starting it from the shell works. But I guess I can convince the script to cooperate ;-) I guess this option could help me a lot regarding the sound problems I got sometimes. Yes, it might help a lot. I will see when doing some calls over sip (there I had the most problems). Maybe at the evening. Now I have to breakfast, shower and go to work. And I need to go to bed!

Jim Van Meggelen schrieb: -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Michael Vogel Is it a little bit too much for such a machine? What could be the bottleneck? CPU? Memory? Interrupts? YES! And by that I mean "all of the above". ;-) Asterisk will run, but the sound quality is almost certainly going to be awful (like a poorly-tuned radio station). By now I only have got sometimes crippled sound. Phonecalls from FXO-device to FXS-device are working perfect. They don't seem to have echos by now. Go ahead and try it if you're just playing around, but if you put it into production, don't bother asking anyone what's wrong when your quality sucks, 'cause you already know the answer. Okay. If you have serious plans for Asterisk, you'll probably want to look at giving it a dedicated server. My "serious" plans are only playing around with it and using it only for my own. Cheers, and best of luck (Asterisk has ben run on less than what you have, so don't be discouraged, just be aware of what you're getting into). Okay. At first I will try to fetch more memory. I hope I can organize some at work (from old machines). Bye!
