This option should usually be left unchanged. Some of the options are not opera-

Left column
► Send T.38 re-INVITE
Activating this option will lead to OfficeMaster Gate initiating the switch to T.38 fax receive. Otherwise
this is handled via the Exchange UM server.
► Voice Activity Detection (VAD)
is the option to stop the transmission of voice data during pauses in the conversation in order to save band -
width („Silence Suppression“). This can also help to avoid echo in certain situations. More on the topic of
echo can be found under „Appendix A: Echo Canceling“ on page ii.
► Packet Time
The Packet Time of 20 milliseconds is standard. A change to the Packet Time has no advantages.
