[asterisk-users] Best timing source?

[Carlos Chavez]

     I am currently having a voice quality problem with one of our 
Asterisk servers.  We have checked the network and we have found no 
problems that could cause the voice to sound cracked and with small 
interruptions.  I am looking at the timing source for Asterisk and it is 
currently using timerfd even though we have an E1 card installed.  Is 
timerfd better than dahdi?  Any recommendations to test if timing may be 
a problem for voice quality and DTMF?
