when a call is already in progress and there is a new incoming call. The

default values are (300, 5000) and 425 respectively.

TXGAIN and RXGAIN are respectively the gain applied to the audio

signal to and from the network. The default values are 0 dB.

IMPEDANCE changes the FXS equivalent circuit that should match the

connected phone one to guarantee the maximum quality and lowest line

echo. The default value is 600R.

Between the network and the FXS interface there is a circular buffer

where BUFLEN is its total length while BUFTHR is the accumulated

voice frame length before they start to be transferred to the FXS

interface. This default value for BUFFLEN and BUFTHR are

respectively 120 and 60 msec.

VAD enable or disable the feature to detect silence period and avoid

sending corresponding frames on the network. By default this

parameter is ON.

The digit collection terminates after a timeout of DIGITTOUT seconds.

The default value is 3 seconds. This timeout can be skipped if the # key

is pressed.

The device can cancel line echo up to 8 msec. The value given is

expressed in 0.125 usec frames so the value 64 corresponds to the

longest echo that can be cancelled.

If a call is placed this can be routed by default to PSTN or to the VOIP

network based on DEFAULTCALL parameters value. The default is

PSTN. If the call must be routed to the not default network, a prefix

must be dialled. The prefix is a one digit corresponding to PREFIX

parameter that has its default value set to “*”.

If there is an incoming call from the PSTN and all the configured phone

ports are engaged in a VoIP call an audible tone is played for CWAITD

seconds, with the same ring cadence.
