[Asterisk-Users] Trunked IAX or not

The test results that Philipp pointed out show some protocol 
comparisons that include "iax2 trunking / alaw" and "iax2 / alaw" and 
concludes that "IAX2 trunking is more than twice as fast as non 
trunking IAX."

Forgive the newbie question, but what is this distinction?  In what 
cases is a connection 'trunking' or 'not'?  If I have a "register =>" 
statement in my iax.conf file, is that a trunked connection to my DiD 
provider?

Thanks!
