G.722 Support
Enable or disable the G.722 codec.
DTMF Detection Type
What type of DTMF events should be detected and processed by the 8190S. If 'Auto' is
selected the 8190S will accept the first DTMF type it receives (RTP telephony, RTP in-
band, or SIP info) and ignore all other types.
Outbound Ring Limit
Typically set to ensure that a call will not reach voicemail. This feature can be used to set
a limit on how long the speaker will ring before timing out
Ringback Tone
Allow audible ringback tone to be played over the speaker until the call is answered.
Allow Call Button to End Active Call
Pressing the call button while a call is active will either end the call or end the call and
redial.
Ambient Noise Compensation
To configure, set the volume to an appropriate level for a quiet environment and enable
the Ambient Noise Compensation. The integrated microphone will measure the ambient
noise during idle periods and automatically increment the speaker volume, if any increase
in background noise is detected. Ambient noise level is averaged over 10 seconds. The
noise compensation will not be functional when playing background music.
Automatic Gain Control (AGC)
Normalizes the audio level. Automatically maximize level of voice received from calling
phone in order to make page volume more consistent.
