Put the VoiceDSP processor into Speakerphone mode, and set the speakerphone to full-duplex
mode.
Set Speakerphone Mode mode
Deactivate the speakerphone, and return the VoiceDSP processor to nor-
mal operation mode.
Put the VoiceDSP processor in speakerphone mode and activate speaker-
phone in full-duplex mode i.e., with full cancellation of both the acoustic
and the electrical echoes. Tone detectors are not active. Gains in the Send
and Receive paths are set by the relevant tunable parameters.
Activate the speakerphone with no echo cancellation (this mode is used
for system tuning).
Activate the speakerphone, while generating silence to the line. The near-
end-listener can hear the far-end-speaker, but not vice versa. Tone detec-
tors are not active.
The line is audible on the speaker. Tone detectors are active. This mode is
used for call generation.
Restart the current speakerphone mode. This mode differs from ON; it does
not require full initialization of the speakerphone. It should be used to re-
sume the speakerphone operation to adjust to an environment change
(e.g., parallel pickup).
Stop the codec interrupts. Neither side can hear each other.
The speakerphone is disabled. Electric echo cancellation is active for the
CAS detection (CIDCW).
