The Phone Settings page allows you to configure control features that
affect a phone connected to a VoIP port.
Figure 50: Phone Settings
The following items are displayed on this page:
Caller ID Block
Check this box to enable a block on the displayed
ID of incoming calls.
Echo Cancellation
Enables a time delay for voice echo cancellation.
A voice echo can be created on some two-wire phone loops, which
becomes increasingly louder and annoying when there is a long delay.
If voice echo is a problem during a call, you can enable this parameter
to try and reduce or remove it.
Voice Activation Detection
Enables the detection of periods of
silence in the audio stream so that they are not transmitted over the
network.
Comfortable Noise Generation
Creates artificial noise for the
listener during detected silent intervals in the audio stream.
Answer Timeout
The time after which a no answer message is sent
to the caller. (Range: 0-60 seconds; Setting of zero disables the
timeout)
Dial Tone Timeout
The length of time a dial tone is heard on a
connected phone. (Range: 0-60 seconds; Setting of zero disables the
timeout)
Inter Digit Timeout
The maximum time delay allowed between
each dialed digit. When the time is exceeded, a call is made using the
dialed digits. (Range: 0-10 seconds; Setting of zero disables the
timeout)
