DSG Technology IPStar, Руководство по эксплуатации

Страница: 54 / 54

During the call, the other party's voice seems slowed or delayed seriously
(more than three seconds).
The bandwidth between the user’s IPStar and the local Internet Service Provider (ISP) is
not enough to support a regular Internet call. Please terminate the Internet connection
and try to place the call again to see if the voice quality has improved. If there is no
improvement, then change to another phone line to see if there is any enhancement of the
voice quality. If the voice quality does not improve, try to set DATA CONTROL in the
Configuration Mode to High and place the call again.
If there are still other problems other than the ones stated above.
It is recommended that users should try to use other Internet Service Providers (ISPs) to
secure the best Internet connection quality.
Appendix B. Troubleshooting
During the call, there is a slight delay while conversing.
This is an expected Internet phone situation. The degree of voice delay depends on the
Internet traffic and the routing path. IPStar’s Dynamic Jitter Buffer Control algorithm
will optimize the delay time automatically in the first ten seconds of the call.
Problems during an Internet Call
During the call, it is difficult to hear the other party.
The Network Percentage Indicator on the LCD screen allows the user to monitor and to
identify if the Internet traffic has become congested. The user may wait to see if the
traffic subsides or press the button to terminate the call and try to place the call
later. If the call cannot be terminated successfully, switch off the power to reset the
IPStar and place the call again.
The button was pressed to terminate the Internet connection but the
LCD screen kept displaying "Please Wait".
IPStar will initiate a connection to DSG IPStar Server before terminating the Internet
connection. If the "Please Wait" message is displayed for over 30 seconds due to the
congested Internet traffic, then turn off the power to reset the IPStar.
