The Name you assign may contain a maximum of 24 characters. Default: Matrix SETU ATA211
• First Digit Wait Timer: The First Digit Wait Timer signifies the time for which the system waits for
receiving the first digit after going Off-hook from the FXS Port. On expiry of this timer, the system will give
error tone to the user. Valid range: 01 to 99 seconds. Default: 15 seconds.
• Inter Digit Wait Timer: Inter Digit Wait Timer signifies the time period for which the system should wait
between two consecutive digits when receiving the digits from the FXS Port. On expiry of this timer, the
number is considered to be complete and is dialed. Refer topic “Dialed Number Table” for information
about End of Dialing while dialing minimum or maximum numbers. Valid range: 01 to 99 seconds. Default:

• Transfer Notification Timer: This is the time for which the system will wait for notification of the status of
a transferred call, i.e. whether the transfer target is busy, has answered, has disconnected, etc. Refer topic

• Play Routing Tone: By default, the system plays routing tone when the call initiated from the FXS / FXO
port is being routed through a SIP Trunk.
SETU ATA211 plays routing tone to the FXS / FXO port user when call is made through the SIP trunk.
You may clear the Play Routing Tone check box, if you do not want the system to play routing tone.
• Call Release Timer: This timer allows the system to release the matured calls made from the FXS port,
FXO port and from SIP trunks after a specified time period.
The Call Release Timer is used for disconnecting calls that remain connected in certain conditions. For
example, the FXS port has disconnected the call, but no disconnect event is received from the SIP trunk.
In this case, the call remains live in the system. On the expiry of the Call Release Timer, this call will be
disconnected.
This Timer may also be used to restrict the duration of calls made from the FXS port, FXO port and SIP
trunks.
To apply this timer, select the Call Release Timer check box and set the Timer to the required duration
from 001 to 999 minutes. Default: 999 Minutes.
• VoIP Silence Disconnect Timer: This feature allows disconnecting the call if silence is detected during
speech, for more than the specified duration.
The SETU ATA211 supports this feature to detect the silence during VoIP calls. If this silence duration
exceeds the specified value, the call will be disconnected.
To apply this timer, select the VoIP Silence Disconnect Timer check box and set the Timer to the
required duration from 001 to 99 minutes. Default: 99 Minutes.
• Forward Error Correction: Forward Error Correction is used for data transmission whereby ATA211 adds
redundant data to its messages, which allows the receiver to detect and correct errors without asking the
sender for additional data.
