I have found that:

1) This is a common problem of other zyxel hardware too (e.g the ATAs).

2) Nobody noticed this HUGE bug because Asterisk make the call start 
even without the ACK! And everybody use Asterisk as SIP server or B2BUA...

Obviously even the zyxel laboratoires use only Asterisk to test their 
hardware!

Anybody (with a better english than mine) have a contact in Zyxel to 
signal the problem?


Bye.
