You cannot retrieve parked calls.
Probable Cause
The first digit of an extension
number matches the first
digit of parked calls.
You hear static, sudden silences, gaps in speech, or garbled speech.
Probable Cause
You may be experiencing
network problems.
A call is forwarded or transferred to an external telephone number and the call is disconnected.
Probable Cause
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.
