It is used to set if the device allows the end users to make an outbound direct IP call.
If it is set to "Yes", the device will hide the IP call feature and end users will not be
allowed to make an outbound direct IP call. No SIP server is required to make quick
direct IP call. The default setting is "No".
It is used to set if the device will automatically fill in the first three octets to make an
outbound direct IP call regardless of subnet mask. If it is set to "Yes", users can dial
an IP address under the same LAN/VPN segment by entering the last octet in the IP
address from its local IP address. The port number used for the target IP address is
5060 by default. Please note the leading 0 in the last octet needs to be omitted.
For example, to make direct IP call to aaa.bbb.ccc.XXX, dial XXX on device directly.
No SIP server is required to make quick direct IP call. The default setting is "No".
It is used to reduce video distortion. If set to "Yes", the GVC3210 will skip the P frame
in lost video packet to decode I frame in the next video packet. The default setting is
"No".
Set the video display mode to "Original proportion", "Equal proportional cutting" or
"Proportional add black edge".

If set to "Original proportion", the device displays video in its original
proportion that received from remote party, if the remote video display
proportion is different from the device, the device will stretch or compress
video to display it.

If set to "Equal proportional cutting", the device will cut video to meet its own
display proportion.

If set to "Proportional add black edge", the device will display video in its
original proportion, if still exists spare space, the device will add black edge
on it.
Note: The default setting is "Equal proportional cutting".
It is used to set what characters will be included in the SIP INVITE URI if end users
input #. If it is set to "Yes", the device will replace the # by %23. Otherwise, it will
include # in the SIP INVITE message. The default setting is "Yes".
Allows users to select whether to enable MUTE on incoming call or outgoing call. If
enabled, the GVC3210 will become automatically muted once the incoming call or
outgoing call is established. Available options are: "Disable", "Auto mute on incoming
call", "Auto mute on outgoing call" and "Auto mute on incoming & outgoing call".
The default setting is "Disable".
If set to "Yes", the voice of knocking table and turning over papers will be eliminated
in call clearance (no one is speaking). The default setting is "Yes".
