Person A: What is the most important thing a comedian needs to know?

Person B: I don't know what is the most....

Person A (interrupts): TIMING!


I believe that /dev/zap/pseudo provides access to timing for Asterisk
components that do not have a reliable clock source, without requiring
or using up an actual voice resource from the zap/dahdi hardware. This
is useful (for example) for Meetme where you can have attendees
arriving and leaving, so cannot rely on anyone as a clock source.

(I hope that is right)
