Warning:
You need to have Internet access information and VoIP Calling Card information

5.1 Receiving Internet call
DPH-70L needs to be connected to VoIP server to receive Internet phone calls. This is called
RECEIVE state. VoIP button enables and disables this state and the corresponding VoIP LED
indicate whether the DPH-70L is in receive state.
When you press the VoIP button, DPH-70L connects to Internet and VoIP (Internet Telephone)
Service Provider. During this connection process, DPH-70L will play progress tone and blink the
VoIP LED. After connecting to the VoIP server, it will turn on the VoIP LED and stop progress
tone. It stays connected to Internet for 15 minutes or until you cancel it by pressing the VoIP
button again.
During this connection process if anything fails, DPH-70L will disconnect modem, turn off VoIP
LED, displays 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-70L 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.

Normal dialing
Like conventional phone, lift the handset, press VoIP button and dial the other party phone
number followed by 'ENTER' key. For example, you press 'VoIP 12345 ENTER' to call 12345
through the Internet. The VoIP button tells the DPH-70L to connect to Internet.
DPH-70L 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 see appropriate error messages. Please refer
Troubleshooting for more information about the error messages.
During the process of establishing Internet call, DPH-70L connects to the Internet and then,
connects to the VoIP service provider. This may take some time unlike normal phone.

number entry into DPH-70L by pressing 'ENTER' key. If you don't press any key for more than 5
