Configures the video display mode to "Original proportion", "Equal
proportional cutting" or "Proportional add black edge". 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 phone, the phone will
stretch or compress video to display it; If set to "Equal proportional cutting",
the phone will cut video to meet its own display proportion; If set to
"Proportional add black edge", the phone will display video in its original
proportion. If it still exists spare space, the phone will add black edge on it.
The default setting is "Equal proportional cutting".
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".
Configures whether to choose Call Progress Tone automatically by region.
If set to "Yes", the phone will configure CPT (Call Progress Tone) according
to different regions automatically. If set to "No", you can manual configure
CPT parameters. The default setting is "No".
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.
