Packetization Time 
You can use the Packetization Time screen to specify definite packetization rates for coders selected in 
the Voice/FAX Parameters screen (in the “Coder Options” group of fields).  The Packetization Time 
screen is accessible under the “Advanced” options entry in the sidebar list of the main VOIP software 
screen.  In dealing with RTP parameters, the Packetization Time screen is closely related to both 
Voice/FAX Parameters and to IP Statistics.  It is located in the “Advanced” group for ease of use. 
 
Packetization time 
Packetization rates can be set separately for each channel. 
The table below presents the ranges and increments for packetization rates. The final column represents

the Copy Channel button on the Packetization Time screen. Simply click the boxes next to the channels 
you wish to copy the settings for.
