We have a scenario with 30 extensions on an elastix box. Now they need call recording for all these users. My question , is there any expected issues (like cpu over load) if all these 30 extensions or 30 simultaneous calls are recorded?
Assuming i have a core2duo cpu with 1 GB RAM and 1 TB HDD.

Please advice.

Regards

There is no real way to know what the limitations of your hardware are until you try it.

Generally if you use a big-enough hammer, even the largest nut can be cracked.

rather than relying on anecdotal or empirical methods, I suggest you install sysstat


yum install sysstat

after a while sar (System Activity Reporting)

sar -A

will start showing all sorts of useful things that might be pertinent like memory use ,
page faulting, interrupt , cpu load, disk io, network io . . .

You will probably be using "man sar" quite a lot as you get comfortable with it.

The logs in /var/log/sa are by default appended to every 10 minutes, rotated daily and retained for a week.
