You cannot retrieve parked
calls.
The first digit of an extension
number matches the first
digit of parked calls.
 Your system administrator may have to correct your Dial
Plan settings. Do not have extension numbers whose first
digits match the park extension prefix.
You hear static, sudden
silences, gaps in speech, or
garbled speech.
You may be experiencing
network problems.
 Your LAN administrator should ensure the following
minimum guidelines are met:
 A switched network topology is recommended (using
standard 10/100 Ethernet switches that carry traffic
at a nominal rate of 100 Mbit/s).
 The office network infrastructure should use Cat5
wiring.
 Do not connect a network server PC to the PC port on the
Deskset.
 Make sure the network cable is solidly plugged in. If you
tug on the cable, the plug should remain inserted.
A call is forwarded or
transferred to an outside
telephone number and the
call is disconnected.
Telephone line to telephone
line call times have been
restricted. Calls that are
forwarded or transferred to
an outside phone number
use two PSTN lines or voice
channels for the duration of
the call. To avoid tying up
two outside lines, these calls
are on a timer.
 Ask your system administrator to reset the Timer for
Forwarded and Transferred Outside Calls.
