Hello to all Im trying to register SIP clients (Cisco IP phone and Planet VIP )that are located behind an ADSL line ( and behind NAT), and the first time they register, they receive the OK from SER, but when I reboot the phone, they cant connect again. They receive "401 Unauthorized" from SER. SER isnt returning "401 Unauthorized" in any part of ser.cfg
Im not using firewall. Can the problem be in the type of NAT?
Can someone help me?
Thanks Joao Pereira
