I am using currently CentOs 5.4 as opertating system and Asterisk® Open Source PBX asterisk 1.6.2.6.
I wan to know by default what is the timing source used by asterisk ? and what is the timing source used by asterisk when asterisk.conf
"internal_timing = yes" is set
I am also not able to build resource module res_timerfd
Why are you using such an obsolete version? I’m not sure if that version supports res_timerfd, but, if it does, the implementation will be buggy. With that version, you should be using dahdi as your timing source.
