You cannot make
international long distance
calls.
Call Appearance mode only—
If
no trunk prefix (digit entered before
dialing outside calls) is set, phone
numbers, including international or
country codes, that start with 0
(zero) will go to the Synapse
system operator.
Consult your system administrator.
You cannot access phone
company services like 411.
Call Appearance mode only—
If
the
PSTN Trunk Prefix
is set to
none
and any x11 extensions
already exist (such as 411, or 611),
then the extensions take
precedence. In other words, dialing
411 calls extension 411, not the
411 directory service. 911 cannot
be assigned as an extension
number.
Consult your system administrator.
Ensure that you enter a 9 or whatever digit, if any,
that must be dialed first for an outside call. For
example, 9-1-555-0123.
The PSTN Trunk reservation
is not being honored.
Call Appearance mode only—An
incoming call may be using that
line. Parking calls and forwarding
calls on a reserved trunk does not
free up the trunk.
Consult your system administrator about setting up
Trunk Routing to reserve the incoming path to the
“special” extension.
A Forwarded call must end before the reserved trunk
is available.
Call Appearance mode
only—I cannot make an
outgoing call on a system
with reserved trunks.
All lines and channels are being
used for active or incoming calls, or
are reserved for other extensions.
If all trunks are reserved, extensions with trunk
reservations cannot make calls. The system
administrator can either remove the reservations
from some trunks or arrange for additional analog
telephone lines or T1 channels.
