Advanced
Packetization Time
You can use the Packetization Time window to specify definite packetization rates for coders selected in the
Voice/FAX Parameters window (in the “Coder Options” group of fields). The Packetization Time window is
accessible under the “Advanced” options entry in the sidebar list of the main VOIP software window. In dealing
with RTP parameters, the Packetization Time window is closely related to both Voice/FAX Parameters and to IP
Statistics. It is located in the “Advanced” group for ease of use.
You can set packetization rates for each channel.
The table that follows presents the ranges and increments for packetization rates. The final column represents
recommended settings (based on the most common found) when operating with third party devices.

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