But then that gets back to my Intel C2D show as two procs. 2 x 2 = 2. Or is C2D not four cores? If I'm not mistaken, there was a Core Duo - which was dual core processor. Now there is a Core 2 Duo - which is a second generation dual core processor. Still just 2 cores though...

I can't speak for Steve's solution (as I'm not sure exactly what he's doing) but I could take a stab in the dark and guess that he's capturing the audio at the network layer (on a completely different box than Asterisk is running on) and recording it from there. But that's just a guess... To address several points: OrecX (http://www.orecx.com/) can do call recording outside of the Asterisk core using several different methods depending on your needs and channeltypes. In fact even with Sangoma TDM cards you can capture audio at the kernel level and send the audio as RTP streams very efficiently(3% CPU load for 92 channels) to an OrecX server on your network. It must be mentioned that setting up Orecx with retrieval might be a little complex for some Asterisk users, especially if you are recording a large amount of calls, or are recording on more than one Asterisk server, and if you choose this route you would do well to hire an experienced consultant(or contact Oreca directly) to do the install for you. As far as Asterisk-based recording, writing to a RAM drive(or tmpfs) is about your only option if you are planning on doing more than 50 concurrent recordings, if you are using Asterisk it is a viable and tested solution. I have several client systems that are recording well over 50 calls concurrently on a daily basis this way. If you will be recording directly to hard drives with any frequency or volume I would strongly recommend NOT using standard IDE or SATA hard drives, they burn up and fast. Use a caching SCSI drive controller with some high quality SCSI drives and you can record to those drives for years even at 40 concurrent channels recording all day every day. Hope that helps, MATT--- I paid for the OrecX ability to save the recordings as the sipcallid. This is fairly easy to track and match up in a CRM so long as you are writing to a DB. Before that you just had a bunch of folders based on day and hour and the filenames were impossible to track, IP address and time I believe. Not much use when recording 15k calls a day. I also worked with Bruno @ Oreca to get their passive recording solution from it's infancy (~10 or so concurrent calls) to a real enterprise solution (maxing at ~200 concurrent recordings per server).

Have a look at the 'flag's in /proc/cpuinfo If there's a 'ht' then it's a hyperthreading core. Otherwise its a 'real' processor, and if there are N on a chip, then well and good. Hyperthreading is like having an extra quarter of a processor, depending on what tasks you're doing. But some BIOSes can disable the HT part of a core, and a modern kernel ought to have hyperthreading support compiled in to make the best use of it. (Another reason I always custom compile kernels for my applications) As far as I'm aware, AMD hasn't made a hyperthreaded core, so it's real cores on the same chip. So if the dual proc, dual core unit above has 2 CPU chips, then it's 4 processors. Going back to Intel: Core 2 is Intels name for that particular family of processors. The 2 in the name does not indicate the number of cores! So you can have a Core 2 Solo - one core, Core 2 Duo - 2 cores and Core 2 Quad - 4 cores.

I disagree. I have a customer running single te410p's in HP DL-380's (I'm pretty sure...) with no audio quality complaints. The DL's only answer, run a couple of AGI's and dial() to a central application server. They frequently max out all 94 channels (ISDN PRI NFAS).

i have HEARD asterisk wasn't made with the idea to run on multi-core processors in mind .. the result was that it uses one core all the time ..so one single P4 3.4 GHZ would perform better than a far more newser quad one. but i might be wrong. but one thing for sure check hardware compatibility before you buy anything. ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Thank you, Just curious, are you recording these calls because that is around the I/O threshold for audio issues when recording all calls. Also, you say no network issues but what is the rating of your switches PPS (often overlooked for speed such as 100mb or 1000mb)?

There are much better solutions than doing a RAM drive. While it may be stable (not in my experience, I advise using different servers for different tasks (with redundancy obviously). A phone switch should be just that, a recording server should also be just that (in demanding environments).

I think its a multi-processor machine, and as i said I might be wrong simply because this bypasses by far my technical knowldge ..

[asterisk-users] Quality problems with ISDN PRI
Hello, We have an Asterisk server with a TE410P Quad-Span togglable E1/T1/J1 card, 3 SPANs configured and OK and one SPAN unconfigured. In our tests it works fine, but when it has a big laod of calls (say, from 40 to 60) we have quality problems: some calls has the sound cut-off (during the call, voice was not stable) The IRQ card is alone, CPU load was not high, network was fine for sure. This server is receiving the calls from SIP channels and routing to the primaries. It's a HP server, multicore, multiCPU. I'm wondering if someone has had these kind of problems (quality problems, sound cut off) with 40 and 60 calls but not with 2 or 3, using Digium cards. Bit later I will call to Digium but I thought that here there is lot of people with lot of experience with these cards.
