Configures tone frequencies according to user preference. By default, the
tones are set to North American frequencies. Frequencies should be
configured with known values to avoid uncomfortable high pitch sounds.
Syntax: f1=val,f2=val [,c=on1/off1[-on2/off2[-on3/off3]]];
(Frequencies are in Hz and cadence on and off are in 10ms)
ON is the period of ringing ("On time" in "ms") while OFF is the period of
silence. In order to set a continuous ring, OFF should be zero. Otherwise
it will ring ON ms and a pause of OFF ms and then repeats the pattern.

Adjusts the call waiting tone volume. Users can select "Low", "Medium" or
"High". The default setting is "Low".
Defines the ring cadence for the phone. The default setting is:
c=2000/4000.
Configures video frame rate for SIP video call from "5 frames/second", "15
frames/second", "25 frames/second" and "30 frames/second". The default
setting is 15 frames/second. The video frame rate is adjustable based on
network conditions. Increasing the frame rate will significantly increase the
amount of data transmitted, therefore consuming more bandwidth. The
video quality will be affected due to packet loss if extra bandwidth is not
allocated.
Sets the video display mode to "Original proportion", "Cut proportionally"
or "Add black margin proportionally".

If set to "Original proportion", the phone displays video in its
original proportion. If the video display proportion is different from
the one of the phones, the phone will stretch or compress video to
display it.

If set to "Cut proportionally" the phone will cut video to meet its
own display proportion.

If set to "Add black margin proportionally", the phone will
display video in its original proportion. If it still exists spare space,
the phone will add black edge on it.
Enables the phone system for frame skipping in video decoder. If it is
enabled, the video decoder will skip the P frame and start decoding from
the next I frame. Enabling this option will help reduce flickering in the video
when the bandwidth is limited in the network environment. The default
setting is "Yes".
