Just a quick update on our progress with the RAM disk solution for
digitally recording large numbers of calls via Monitor. We are
currently recording approximately 80 - 100 concurrent calls to the PCM
format on our production server. We also have over 220 dynamic agents
logged into 10 queues handling calls across 4 offices (1 local, 3
remote). All of our calls are SIP to SIP (a Cisco AS5400 terminates
our Ts) using the u-Law codec and we do no transcoding or DSP on the
Asterisk box. Yesterday, a total of over 8300 calls were handled. The
box is running roughly 77% - 80% idle.<br>
<br>
As we add more clients to the box, I'll update the list with the
results.<br>
<br>

Are you running software RAID by chance with your SATA? SCSI or SCSI
Raid will not each CPU near as much since the HBA does all the work and
does tie up the CPU with all its I/O's. We have successfulyl recorded
5+ calls at a time via dual xeon 3.0 with 10K SCSI drives in RAID-5
with no issuses running about 30 PRI channels and anywhere from 50-75
SIP channels, all with g729 encoding.<br>
<br>
Hope this helps!<br>

I tried it and indeed, it lowers cpu usage, so I switched from wav to<br>
gsm format and Im thinking about doing the ramdisk solution for
recording...<br>
Sounds like a good move?</blockquote>
