4 Internet Phone Calls
After basic configuration, DPH-70 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 DPH-70 to make and receive Internet calls.
4.1 Receiving Internet call
DPH-70 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 DPH-70 is in receive state.
When you press the DIAL-UP button, DPH-70 connects to Internet and VoIP (Internet Telephone)
Service Provider. During this connection process, DPH-70 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, dph-70 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, DPH-70 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 DPH-70 to connect to Internet.
DPH-70 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
Troubleshooting for more information about the error messages.
During the process of establishing Internet call, DPH-70 connects to the Internet and then,
connects to the VoIP service provider. This may take some time unlike normal phone.
Warning:
DPH-70 identifies end of phone number by '#'. Please terminate phone number entry
into DPH-70 by pressing '#' key. If you don't press any key for more than 5 sec, DPH-70 identifies
it as end of phone number.
