Advanced Settings/General Settings
Local RTP Port
This parameter defines the local RTP-RTCP port pair used to listen and
transmit. It is the base RTP port for channel 0. When configured, for audio,
channel 0 will use this port _value for RTP and the port_value+1 for its
RTCP; channel 1 will use port_value+4 for RTP and port_value+5 for its
RTCP. For video, channel 0 will use port_value+2 for RTP and port_value+3
for its RTCP; channel 1 will use port_value+6 for RTP and port_value+7 for
RTCP. The default value is 5004.
Use Random Port
When set to Yes, this parameter will force random generation of both the
local SIP and RTP ports. This is usually necessary when multiple
GXV-3175s are behind the same full cone NAT. The Default setting is Yes.
(This parameter must be set to No before Direct IP Calling will work)
Keep-alive Intervals (s)
This parameter specifies how often the GXV3175sends a blank UDP packet
to the
SIP server in order to keep the “ping hole” on the NAT router to open.
The default setting is 20 seconds.
STUN Server
The IP address or Domain name of the STUN server. STUN resolution
results are displayed in the STATUS page of the Web UI. Only
non-symmetric NAT routers work with STUN.
Default STUN server: stun.ipvideotalk.com
