ADVANCED SETTINGS PAGE DEFINITIONS
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 por1 for its
RTCP; channel 1 will use por4 for RTP and por5 for its
RTCP. For video, channel 0 will use por2 for RTP and
por3 for its RTCP; channel 1 will use por6 for RTP and
por7 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-

parameter must be set to NO before Direct IP Calling will work)

This parameter specifies how often the GXV-3175 sends 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.

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
