i was looking at an info in the Quintum site, the page is this http://www.quintum.com/main/e_tech_nat.php3
this is why a was asking this info for, i don’t know if this NATAccess is for the Tenor A800, Mark you’ve been of so much help but as i write before in a post, my boss is a cheap bastar and don’t want to buy a Call Relay.
if this NATAccess if for the quintum i just need to figured out how it works.
