Call Rate
Change Call Rate
Finally, change the call rate by
moving the slider.
This can only be done before you call
someone.
Tap More (
) to gain access to the
options.
Then tap Call Rate.
Call rate is the term used to express
the amount of bandwidth allocated
to the call and is measured in kbps
(kilobits per second).
The higher the call rate is, the
better the quality will be, but on
the expense of higher bandwidth
consumption.
The system comes with a default
call rate. This is set by your video
support team as a part of the
Administrator Settings (password
protected).
Why would you like to temporarily
change this setting? In most cases
you will use it to avoid choking
the video call when you try to call
someone at a higher rate than their
system and connection support.
Call rate cannot be changed during
a call, but you may change it just
before you place a call, as outlined
here.
