I try to get a Linksys PAP2 to work but always after 22 sec. the call disconnect.
I know the Cisco Router is the problem because when I switch back to my old DSL-Modem it works fine.
I used the Cisco Software to configure a NAT for the Ports 5004 and 5060 but it still disconnect.
Please Help me out :)
