[asterisk-users] Internal timing under load is critical ?

[babak]

Hi
I am evaluating some voice broadcasting solutions based on Asterisks for more than 1000 simultaneous calls.
Connection to Asterisk all are based on SIP and SIP Trunks so no DAHDI hardware is required.
According to some recommendations like http://osdial.org/howto/  "Internal timing is very critical with Asterisk when it is under load"
and we must use DAHDI hardware or "USB Voice Synch Tool" http://www.sangoma.com/accessories/specialty-tools/
But according to my understanding of wiki https://wiki.asterisk.org/wiki/display/AST/Timing+Interfaces
It seems it is not necessary now.
Please tell me your opinions.

Regards
