22. Relay Latch Commands
When set to "Enabled" the Remote Access Operation Commands to Un-Latch or Latch the relay are enabled.
When set to "Disable" the Remote Access Operation Commands to Un-Latch or Latch the relay are disabled. Disabling
the Latch commands can be useful in applications where you want to eliminate the possibility of inadvertently entering
a latch command leaving a gate open/closed, etc. The relays can still be activated with the "Relay Activation Command"
for momentary closures. Factory Setting: Enabled
23. In-Band Audio Call Progress
The In-Band Audio Call Progress Detection can be set to enabled or disabled. In-Band Audio Call Progress detection
should be enabled in applications where you are making an outbound call through your VoIP phone system and are
relying on In-Band analog audio for ringback or busy detection. Factory Setting: Enabled.
24. In-Band Audio Detect Sensitivity
The In-Band Audio Detect level (Sensitivity) can be set from 1 - 9, 1 = minimum setting, 9 = highest setting. Increasing
or decreasing the sensitivity may be required in applications where you are making an outbound call through your VoIP
phone system and are relying on In-Band analog audio detection. Factory Setting: 5
25. Call Length Time Out
This feature selects the maximum length of time that calls can be connected. Programmable in increments of 1 minute
up to a maximum of 9 minutes or disabled. With the call length disabled, the K-1200-IP phone must rely on a call
ended signal, busy signal, Ring No Answer limit, or touch tone "#" command to hang-up. Factory Setting: 3 minutes
Note: Timer starts after call is connected. If call is not answered (and ring no answer disabled) there is a default 7
minute timer.
26. Talk / Listen Delay (VOX)
This feature selects switching time between talk and listen modes (VOX switching time). The Talk/Listen Delay can be
programmed from 0.1 - 0.9 seconds. Factory Setting: 0.5 seconds
27. Speaker Mode
The Speaker Mode will be set to one of the following two modes. This is selected automatically based on Inbound Call
Mode.
OFF/Silent Monitoring Mode: In the "OFF" mode the speaker is disabled on inbound calls. However, the speaker
can be enabled after communication has been established by entering touch tone command "9#". The speaker will
then remain on for the duration of the call.
ON (Factory Setting): In the "ON" mode the speaker is enabled during In-bound and Out-bound calls.
28. Speaker Volume
The speaker volume can be set from 0 - 9, 0 = lowest volume setting, 9 = highest volume setting. Alternatively the
speaker can be turned off for silent monitoring (see Speaker Mode section 27). Factory Setting: 3
29. Microphone Volume / Automatic Noise Cancelling Mode
The microphone volume can be set from 1 - 9, 1 = lowest volume setting, 9 = the highest volume setting. Alternatively
the microphone can be placed in the "Auto" (Automatic Noise Cancelling) mode. With the mic in the Auto mode, when
background noise increases, the mic gain will automatically decrease. When background noise decreases the mic gain
will automatically increase. The Auto mode is useful in applications where the background noise level can change
drastically such as a gas car running vs a diesel truck. Factory Setting: 5 seconds
