Note: Users can choose only 2 of these functions to be shown on the call
interface during a conference.
Mute Key Functions
While Idle
This feature allows the user to configure what mute button will do when
pressed in idle state. If set to “DND”, pressing the mute button will not
receive any incoming calls. If set to “Mute when idle”, pressing the mute
button will mute answered calls. If set to “Disabled”
Call Function Button
Display Timeout (s)
Configures the timeout period for call function buttons display. If set to “0”,
the buttons will be always displayed. The value range is 0-30 seconds.
Auto Config CPT by Region
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 manually configure CPT parameters.
The default setting is “No”.
Call Progress Tones:
● Dial Tone
● Second Dial Tone
● Ring Back Tone
● Busy Tone
● Reorder Tone
● Confirmation Tone
● Call-Waiting Tone
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.

tones: https://www.itu.int/ITU-T/inr/forms/files/tones-0203.pdf
Call-Waiting Tone Gain
Adjusts the call waiting tone volume. Users can select “Low”, “Medium” or
“High”. The default setting is “Low”.
Default Ring Cadence Defines the ring cadence for the phone. The default setting is: c=2000/4000.
Video Frame Rate
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.
Video Display Mode
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.
