Description
Parameter
Enables to insert the rport parameter into the VIA header of SIP
responses if the received-from IP and VIA sent-by IP values differ.
Default: No
Insert VIA rport
Enables the user to use NAT-mapped IP:port values in the VIA header.
Default: No
Substitute VIA Addr
Enables to send responses to the request source port instead of the VIA
sent-by port.
Default: No
Send Resp To Src Port
Enables the use of STUN to discover NAT mapping.
Default: No
STUN Enable
If the STUN Enable feature is enabled and a valid STUN server is
available, the phone 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 phone detects symmetric NAT or a
symmetric firewall, NAT mapping is disabled.
Default: No
STUN Test Enable
IP address or fully-qualified domain name of the STUN server to contact
for NAT mapping discovery. You can use a public STUN server or set
up your own STUN server.
Default: Blank
STUN Server
External IP address to substitute for the actual IP address of phone in
all outgoing SIP messages. If 0.0.0.0 is specified, no IP address
substitution is performed.
If this parameter is specified, phone assumes this IP address when
generating SIP messages and SDP (if NAT Mapping is enabled for that
line).
Default: Blank
EXT IP
External port mapping number of the RTP Port Minimum number. If
this value is not zero, the RTP port number in all outgoing SIP messages
is substituted for the corresponding port value in the external RTP port
range.
Default: 0
EXT RTP Port Min
Interval between NAT-mapping keep alive messages.
Default: 15
