Chapter 3 Phone Use and Configuration Note: Enter any advanced SIP configuration information as it was given to you by your SIP service provider. If you do not have any advanced configuration information, you can skip this section. Figure 5 Advanced SIP Settings (part 1) The following table describes the labels in this screen. Table 2 SIP Setting LABEL DESCRIPTION SIP Port Enter the port number on your ZyXEL Device that SIP calls made with the selected phone should use. Media Port Enter the port number on your ZyXEL Device that RTP media packets should use. Packetization Select the voice codec packetization interval in milliseconds. The default is 20 ms. This is used to minimize loss that happens during transmission of voice data over the network. The packetization interval effectivately sets the size of each voice sample contained within a data packet. At 20 ms, the codec employed in digitizing the voice signal can usually compensate for data degredation and attenuation by using Packet Loss Concealment (PLC). However, if the loss becomes too great, noticeable distortion occurs. Setting the packetization interval higher, however, may introduce more problems depending on the codec (such as G.711). Other codecs (such as G.729 and G.723) have improved PLC techniques and as such can also withstand a higher packetization interval; this means more packets can be lost in transit without a noticeable loss in quality.

SIP Port
Enter the port number on your ZyXEL Device that SIP calls made with
the selected phone should use.
Media Port
Enter the port number on your ZyXEL Device that RTP media packets
should use.
Packetization
Select the voice codec packetization interval in milliseconds. The default
is 20 ms. This is used to minimize loss that happens during
transmission of voice data over the network.
The packetization interval effectivately sets the size of each voice
sample contained within a data packet. At 20 ms, the codec employed
in digitizing the voice signal can usually compensate for data
degredation and attenuation by using Packet Loss Concealment (PLC).
However, if the loss becomes too great, noticeable distortion occurs.
Setting the packetization interval higher, however, may introduce more
problems depending on the codec (such as G.711). Other codecs (such
as G.729 and G.723) have improved PLC techniques and as such can
also withstand a higher packetization interval; this means more packets
can be lost in transit without a noticeable loss in quality.
