Table 33 Call Timer Behaviors

Audio Settings

Audio Settings enable you to affect the network impact of your audio
packets by enabling or disabling compression, silence suppression, and
echo suppression. You can enable and disable these settings for the entire
system and then override the system-wide setting for individual devices.
Compression Overview
Before voice traffic can be transmitted over a digital network, the audio
waveform, an analog signal, must be encoded into a digital format. The
digitized audio is packetized and delivered over the network to a
destination, and then decoded back into a voice waveform. Software
called a codec (coder/decoder) converts the audio information between
digital and analog formats.
Digitized audio formats have different properties. Each format represents
a compromise between bandwidth and audio quality, that is, high quality
audio typically requires more network bandwidth. Compressing the
digitized audio data can conserve bandwidth with little compromise in
audio quality, but compression requires increased processing overhead
when encoding and decoding the audio information. Too much
processing overhead can introduce delay.
Feature Description
Transfer If the calling party calls the main Auto Attendant number, and the
Through Auto Auto Attendant transfers the call to the extension of choice (or to
Attendant the default destination), then the called party sees the same
behavior as if the call had been transferred. That is, the Call Timer
count at the transfer destination starts when the called party
answers the call.
Bridged Calls For bridged calls, the Call Timer display depends on the off-hook
indicator. For example, if an administrative assistant answers the
phone, puts the call on hold, and a site manager picks up, the
manager sees the counter start from zero. However, if the
administrative assistant puts the call on hold and retrieves it later,
then the administrative assistant would see that the NBX system has
defined the Call Timer display for normal hold.
As another example, suppose the administrative assistant puts the
call on hold, the manager picks up the call, and then puts the call
on hold. At this point, the administrative assistant picks up the call.
In this case, the administrative assistant sees the Call Timer display
as if the administrative assistant had picked up a new call.
