SIP Device Parameters
SIP: Select whether you wish to use SIP as VoIP call signaling protocol. The default setting is Disable.
Silence Suppression (VAD): Voice Activation Detection (VAD) prevents the transmission of silence
since it will unnecessarily consume your bandwidth. This function is also known as Silence Suppression,
and it is a software application that ensures the bandwidth is used only when voice activity is activated.
The default setting is Enable.
Echo Cancellation: G.168 echo cancellation is an ITU-T standard. It is used for removing the echo while
you are on the phone. If it is enabled, this will mean that you will not hear too much of your own voice on
the phone while you talk. The default setting is Enable.
RTP Port: Provide the base value for the media (RTP) ports. These ports are assigned to various
endpoints and the different call sessions that may exist within an end-point. (Range from 5100 to 65535,
default value is 5100)
Region: This selection is a drop-down box, which allows user to select the country for which the VoIP
device must work. When a country is selected, the country parameters are automatically loaded.
Voice QoS,: Differentiated Services Code Point (DSCP), it is the first 6 bits in the ToS byte. DSCP
Marking allows users to assign specific application traffic to be executed in priority by backbone Routers,
based on the DSCP value. See Table 4. The DSCP Mapping Table:
