default setting is 20 seconds. The valid range is from 10 to 160.
STUN Server
Configures the URI of STUN (Simple Traversal of UDP for NAT) server.
The phone system 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”.

Sets the phone system to automatically fills in the first three octets to make
an outbound IP call. 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.
To dial quick IP call, offhook the phone and dial XXX (X is 0-9 and XXX
<=255), the phone will make direct IP call to aaa.bbb.ccc.XXX where
aaa.bbb.ccc comes from the local IP address REGARDLESS of subnet
mask. XX or X are also valid so leading 0 is not required (but OK). No SIP
server is required to make quick IP call. This setting can be configured after
enabling ‘Use Direct IP Call Mode option. The default setting is “No”.
