Synapse SB67035 Deskset User’s Guide
Back to Contents
On external calls, you hear an excessive echo at the Deskset.
You cannot retrieve parked calls.
You hear static, sudden silences, gaps in speech, or garbled speech.
A call is forwarded or transferred to an external telephone number and the call is disconnected.
Probable Cause
Corrective Action
The automatic PSTN Gateway
line calibration did not run
properly.
See your system administrator. There may be
non-system equipment connected in parallel to
the telephone line.
Probable Cause
Corrective Action
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.
Probable Cause
Corrective Action
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
Cat.-5 wiring.
Do not connect a network server PC to the PC
port on the Deskset.
Make sure the network cable is securely plugged
in. If you tug on the cable, the plug should remain
inserted.
Probable Cause
Corrective Action
Telephone line-to-telephone
line call times have been
restricted. Calls that are
forwarded or transferred to
an external 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.
Contact your system administrator about
resetting the
Timer for Forwarded and
Transferred Outside Calls
.
