The quality will be the same as a conventional telephone line; however, the quality of IP phone can be easily affected by your Internet environment. If you use IP phone service under the following conditions, the quality will be affected.
When Internet traffic is extremely high.
When the downstream speed for FLET'S ADSL/B FLET'S/FLET'S HIKARI NEXT/FLET'S HIKARI PREMIUM is below 500kbps.
During the heavy use period at night (about 11:00p.m. to 1:00a.m.)
When you are downloading large amounts of data via Internet.
When there is a protective device which affects ADSL connection, you may feel that the quality is degraded so much it's like being put on hold or disconnected.
When there are some appliances which generate strong electromagnetic waves around the telephone line.
Security is enhanced by UserID and password but cannot be assured completely since IP-phone uses IP Networks. Please use your landline for highly confidential calls.
