5 PSTN Phone Calls
DUV1000 can make and receive normal PSTN phone calls. When DUV1000 is not connected to
the Internet through the DIAL-UP button (RECEIVE state), it is known to be in idle state. In this
state it works as a normal phone, making and receiving PSTN phone calls. This feature does not
need any configuration.
5.1 Making PSTN call
To make an outgoing call, go off hook and dial the destination number, followed by #. For
example, you press 12345# to call 12345 through PSTN network. It plays various call progress
tone as in normal phone and plays ring back tone if the called party is free. DUV1000 establishes
the call on called party attending the call.
The dialing mode of PSTN number depends upon configuration of ISP number. If ISP number is
configured with & (for BLIND DIALING), PSTN number is also dialed in blind mode, and if ISP
number is configured with $ (for PULSE MODE DIALING), PSTN number is also dialed in pulse
mode.
DUV1000 has special supports for operation behind an EPABX. For example, you may have to
dial 9 to get external dial tone and then dial the destination number. In this scenario, first dial ‘9#’
to dial to EPABX and get external dial tone, then dial the destination number.
Warning: DUV1000 identifies end of phone number by ‘#’. Please terminate phone number
entry by pressing ‘#’ key. If you don’t press any key for more than 5 sec, DUV1000 identifies it as
end of phone number.
5.2 Receiving PSTN call
DUV1000 can receive any normal PSTN phone call when DUV1000 is not connected to the
Internet through the DIAL-UP button. It rings on incoming call and establishes call on off hook.
Either party can disconnect the call by going on hook.
5.3 Transferring PSTN call
This feature allows the user to transfer a PSTN phone call to any PSTN phone. To transfer the
call, you flash the hook for a short period and dial the destination number followed by ‘#’. The
destination number will ring and on off-hook the call transfer will be complete.
