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+6
for RTP and port_value+7 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+8 for RTP and
port_value+9 for RTCP. The default value is 5004.
When set to "Yes", this parameter will force random generation of both the local SIP
and RTP ports. This is usually necessary when multiple devices are behind the same
full cone NAT. The default setting is "No".
Note:
This parameter must be set to "No" for Direct IP Calling to work.
It will enable/disable the device to omit the DTMF digits displaying on the TV screen.
The default setting is "No".
If set to "Yes", the Remote-Control app can be paired to the GVC3210 via Bluetooth,
but it cannot connect to the GVC3210 to perform any operations. The default setting
is "No".
It is used to specify how often the device will send a Binding Request packet to the
SIP server in order to keep the "ping hole" on the NAT router to open. The default
setting is 20 seconds. The valid range is from 10 to 160.
It is used to configure the URI of STUN (Simple Traversal of UDP for NAT) /
TURN (Traversal Using Relays around NAT) server. The device will send
STUN Binding Request packet to the STUN server to learn the public IP
address of its network. Only non-symmetric NAT routers work with STUN.
The default setting is "stun.ipvideotalk.com".
It is used to configure the username for TURN server.
It is used to configure the password for TURN server.
It is used to configure the IP address for the Contact header and Connection
Information in the SIP/SDP message. It should ONLY be used if it's required by your
ITSP. The default setting is keep the box blank.
