'show timer' shows all loaded timer modules. That shows none are loaded.

CORE_SOFTTIMER_MODULE is the soft timer built into the FS core... it may or may not use timerfd, depending on your system.

You pick which timer to actually use in your configuration files... for example the rtp-timer-name Sofia profile param.

Use the timer_test command to see which timer actually works best for you (ie most accurate, least jitter).
