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
