4 Internet Phone Calls
After basic configuration, DUV1000 allows you to make and receive Internet phone calls as
described in this section. DIAL-UP button distinguishes the Internet phone call from normal PSTN
phone call. To make Internet phone call press DIAL-UP button followed by destination telephone
number. It supports a user-friendly dialing method as described below.
Warning: You need to have Internet access information and VoIP calling card information
configured in DUV1000 to make and receive Internet calls.
4.1 Receiving Internet call
DUV1000 needs to be connected to VoIP server to receive Internet phone calls. This is called
RECEIVE state. DIAL-UP button enables and disables this state and the corresponding Dial Up
LED indicate whether the DUV1000 is in receive state.
When you press the DIAL-UP button, DUV1000 connects to Internet and VoIP (Internet
Telephone) Service Provider. During this connection process, DUV1000 will play progress tone
and blink the DIAL-UP LED. After connecting to the VoIP server, it will turn on the DIAL-UP LED
and stop progress tone. It stays connected to Internet for 15 minutes or until you cancel it by
pressing the DIAL-UP button again.
During this connection process if anything fails, DUV1000 will disconnect modem, turn off Dial Up
LED, plays an error message, and then goes to idle state. If the Internet access line is busy it will
retry 4 times before giving up.
Warning: In RECEIVE state, DUV1000 is connected to the Internet and you will be charged for
Internet access. Do not leave the phone in RECEIVE mode unless you are expecting an Internet
phone call.
4.2 Making Internet call
4.2.1 Normal dialing
Like conventional phone, lift the handset, press DIAL-UP button and dial the other party phone
number followed by ‘#’ key. For example, you press ‘dial-up12345#’ to call 12345 through the
Internet. The DIAL-UP button tells the DUV1000 to connect to Internet.
DUV1000 plays progress tone and establishes call with the called party. You will hear ringing
tone if the called phone is free and reachable. When the called party attends the call, you can talk
to him. If anything goes wrong you will hear appropriate error messages. Please refer
to
Appendix B: Troubleshooting for more information about the error messages.
During the process of establishing Internet call, DUV1000 connects to the Internet and then,
connects to the VoIP service provider. This may take some time unlike normal phone.
Warning:
DUV1000 identifies end of phone number by ‘#’. Please terminate phone number
entry into DUV1000 by pressing ‘#’ key. If you don’t press any key for more than 5 sec, DUV1000
identifies it as end of phone number.
