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 rates can be set separately for each channel.
The table below 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.
Packetization Ranges and Increments | Recommendations | |||
Coder Types | Range (in Kbps); {default} | Increments (in Kbps) | Setting (in ms) | |
G711, G726, G727 | {5} | 5 | 20 | |
G723 | {30} | 30 | 30 | |
G729 | {10} | 10 | 20 | |

Once the packetization rate has been set for one channel, it can be copied into other channels by using the Copy Channel button on the Packetization Time screen. Simply click the boxes next to the channels you wish to copy the settings for.
