Hello to all Did you ever made it to put a Cisco phone (Cisco IP phone 7940 with SIP) behind ADSL (and NAT) and make calls?? Im trying to do it, and with X-Lite I can place calls, but with the Cisco phone I cant... :( I already putted the NAT= yes in the Cisco Phone. Is there any way of doing this ?
