Handle VIA rport
If you select yes, the WRP500 processes the rport parameter in the
VIA header (this value is inserted by the server in a response to
anyone of its requests). If you select no, the parameter is ignored.
Select
yes
or
no
from the drop-down menu.
The default is
no
.
Insert VIA received
Inserts the received parameter into the VIA header of SIP responses
if the received-from IP and VIA sent-by IP values differ. Select yes
or no from the drop-down menu.
The default is
no
.
Insert VIA rport
Inserts the parameter into the VIA header of SIP responses if the
received-from IP and VIA sent-by IP values differ. Select yes or no
from the drop-down menu.
The default is
no
.
Substitute VIA Addr
Lets you use NAT-mapped IP:port values in the VIA header. Select
yes or no from the drop-down menu.
The default is
no
.
Send Resp To Src Port Sends responses to the request source port instead of the VIA
sent-by port. Select yes or no from the drop-down menu.
The default is

STUN Enable
Enables the use of STUN to discover NAT mapping. Select yes or
no from the drop-down menu.
The default is
no
.
STUN Test Enable
If the STUN Enable feature is enabled and a valid STUN server is
available, the WRP500 can perform a NAT-type discovery
operation when it powers on. It contacts the configured STUN
server, and the result of the discovery is reported in a Warning
header in all subsequent REGISTER requests. If the WRP500
detects symmetric NAT or a symmetric firewall, NAT mapping is
disabled.
The default is
no
.
STUN Server
IP address or fully-qualified domain name of the STUN server to
contact for NAT mapping discovery.
