Model 8602 User Guide
Audio quality is bad while
using a headset (
cnt’d )
The network connection may
not be of sufficient quality to
maintain good quality audio. While on a call with poor audio,
look at the 8602's Status Informa-
tion page. Look for the “Percent
Packets Lost Since Last RTCP,”
“Receive RTP Cumulative Lost
Packet Count,” and “Interarrival
Jitter (ms)” values. If packets are
being lost or the jitter value is high
(i.e., above 80 ms), then the audio
quality is being impacted by poor
network performance.
The Model 8602 is not
maintaining its connec-
tion to the IPRC/IPRA;
possibly reporting that the
connection to Call Pro-
cessing has timed out. The network connection may
not be of sufficient quality to
maintain a steady connection
with Call Processing. Verify the computer’s network con-
nectivity. If a good consistent net-
work connection cannot be
maintained, the Model 8602 will
not be able to operate properly
The Model 8602’s con-
nection to Call Processing
is lost about 10 seconds
after connecting every
time it is started. Another Model 8602 is running
with the same configuration
(i.e., same Device ID and com-
municating with the same
IPRC/IPRA). Shut down one of the Model 8602
applications that has the same
configuration. Make sure that
every user has a unique Device ID
programmed in Call Processing. If
using the Model 8602 with the
same configuration on multiple
computers, then make sure that
the Model 8602 application is dis-
connected before trying to connect
from the other computer.
The “application failed to
initialize properly” error
message appears when
trying to start the Model
8602. The .NET Framework is not
installed on this computer. Install the latest 1.1 version of the
.NET Framework from the
Microsoft Windows Update Web
site.
An active call is dropped. You have walked out of range
from the base of the wireless
headset. Make sure to stay within the range
limits of your wireless headset.
