<FONT FACE="Monaco, Courier New"><SPAN STYLE='font-size:11pt'>Actually it defaults to using timerfd if its enabled in your kernel.... There should be no debate on that, I reviewed that code with tony...<BR>
<BR>
If you don’t have a timerfd enabled kernel it uses the old default soft timer... No you cant tell the difference in there currently with just a show timer command, however that’s likely to change...<BR>
<BR>
Are you running like centos6 or debian squeeze with a stock kernel? Then you likely have timerfd and are using it unless you changed the configs to do something else...<BR>
<BR>
Theres always a lot of debate around this, but the fact is, unless you are seeing crappy audio issues, you probably shouldn’t mess with the timers<BR>

CORE_SOFTTIMER_MODULE is the soft timer built into the FS core... it may or may not use timerfd, depending on your system.<BR>
<BR>
You pick which timer to actually use in your configuration files... for example the rtp-timer-name Sofia profile param.<BR>
<BR>
Use the timer_test command to see which timer actually works best for you (ie most accurate, least jitter).<BR>
