Select the packetization rate for the voice
portion of RTP packets. Configure a value in
10 millisecond increments, from 10 to 40
milliseconds. The default is 20 milliseconds for
all codecs.
Echo suppression reduces the possibility that
you hear your own voice while you engage in a
WiFi call.
On HTC TyTn and 6800 devices, echo
suppression automatically enables when you
use the system speaker and automatically
disables when you use the ear piece. You
cannot change this operation; nor can you
enable or disable the "Echo Suppression"
parameter.
On all other devices, you can enable and
disable the "Echo Suppression" parameter if
the MCC 3100 for Windows Mobile does not
engage in a call.
When you enable "Echo Suppression", the
following settings take effect:
• maximum echo suppression for WiFi calls
• half-duplex audio through the system
speaker
When you disable "Echo Suppression", the
following settings take effect:
• no echo suppression for WiFi calls
• full-duplex audio through the system
speaker
