4 Internet Phone Calls
After basic configuration, DPH-70 allows you to make and receive phone calls as described in
this section. The DIAL-UP button distinguishes Internet phone calls from normal PSTN calls. To
make an Internet phone call press the DIAL-UP button followed by the destination telephone
number. The DPH-70 supports a user-friendly dialing method as described below.
Reminder
:
You must have Internet access information and VoIP calling card information
configured in the DPH-70 to make and receive Internet calls.
4.1 To Make an Internet call
4.1.1 Normal dialing
As with a conventional phone, lift the handset, press the DIAL UP button and dial the other party’s
phone number followed by the ‘#’ key. For example, you press ‘dial-up12345#’ to call 12345
through the Internet. The DIAL-UP button tells the DPH-70 to connect to the Internet.
The DPH-70 will play a progress tone and establish contact with the called party. You will hear a
ring tone if the called phone is free and reachable. When the called party answers, you can carry
on a normal phone conversation. 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 an Internet call, DPH-70 connects to the Internet and then,
connects to the VoIP service provider. This may take some time, unlike a normal phone.
Reminder:
The DPH-70 identifies the last digit of a phone number by ‘#’. Make sure to terminate
a phone number entry by pressing the ‘#’ key. If you don’t press any key for more than 5 seconds,
DPH-70 identifies it as the end of a phone number.
4.1.2 Multiple Calls
RECEIVE state allows you to make multiple Internet calls without connecting to the Internet each
time. You press DIAL-UP to go to RECEIVE state; please refer to the section on “Receiving
Internet Calls” for more details.
In this mode, you just dial the phone number followed by ‘#’. Since DPH-70 is already connected
to Internet, you do not press the DIAL-UP button before dialing a number. For example, you press
‘12345#’ to dial 12345 through Internet. It remains in call-receive state after the end of each call.
Please note that you cannot make normal PSTN call while DPH-70 is in RECEIVE state.
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.
4.1.3 Special Dialing
A dial-up connection sometimes takes time to connect to the Internet depending on the Internet
access line availability and network congestion. Your DPH-70 is designed with a user-friendly
dialing method to help you in such situations.
Dial in the one-hand mode. When you press the DIAL UP button and dial a number without lifting
the handset, the speaker is turned ON. If the DPH-70 establishes contact with the called party it
