DESCRIPTION
Select this if your VoIP service provider has a SIP outbound server to
handle voice calls. This allows the ZyXEL Device to work with any type
of NAT router and eliminates the need for STUN or a SIP ALG. Turn off
any SIP ALG on a NAT router in front of the ZyXEL Device to keep it
from re-translating the IP address (since this is already handled by the
outbound proxy server).
Enter the IP address or domain name of the SIP outbound proxy server,
if your VoIP service provider gave you one. You can use up to 95
printable ASCII characters.
Enter the SIP outbound proxy server's listening port number, if your
VoIP service provider gave you one.
Enter the user name for registering this SIP account, exactly as it was
given to you. You can use up to 127 printable ASCII characters.
Enter the password for registering this SIP account, exactly as it was
given to you. You can use up to 127 printable ASCII Extended set
characters.
