This can happened if you turn on the device after you have not used it for a long
time.
This is not related to the product life time and performance, thus please leave
power on for a while, then the lines will disappear.
This can happen when talking on the phone for an extended period. More power is
used which produces heat. To help reduce heating, the user should take action by
hanging up for a short time.
Be sure the phone is not in Mute mode.
This can happen when your number is registered in a same pickup group. You
need to contact either network administrator or your service provider.
IP Phones voice quality is affected by network conditions. Depending on network
congestion, voice quality can be degraded.
Check server setup, or OS. If there is a network issue, please contact your network
administrator. If it is a network related issue, this may be a service provider's issue,
then contact your service provider to resolve the problem.
Check the ring tone volume with the Volume icon.
