5.1 Receiving Internet call
DPH-70E 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-70E is in receive state.
When you press the VoIP button, DPH-70E connects to Internet and VoIP (Internet Telephone)
Service Provider. During this connection process, DPH-70E 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-70E will disconnect modem, turn off VoIP
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-70E 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.

number followed by ENTER key. For example, you press 'VoIP 12345 ENTER ' to call 12345
through the Internet. The VoIP button tells the DPH-70E to connect to Internet.
DPH-70E 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

During the process of establishing Internet call, DPH-70E connects to the Internet and then,

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