Error message occurs
when placing an ISDN
(H.230) call.
An ISDN cause code is
received from the ISDN
line.
Try the call again.
For more information, see
Q.850 Cause Codes
on
page
Appendix-5
.
The highest-numbered
channel did not connect.
The system cannot make a
call if this channel does not
connect.
Be sure you are calling the correct number. The
number may need to include:
•
A digit for an outside line
•
A long distance access code
•
An international access code
•
A country code
•
An area code or city code
Check that all network cables are properly
connected.
Power off the system, wait five seconds, and power
on the system. Then wait about two minutes to allow
the ISDN lines to resynchronize.
Ask the person at the far site to call your system.
The ISDN switch type is not
configured correctly on the
V500 system.
Check the ISDN configuration and verify with your
ISDN service provider that the system is configured
correctly.
Cannot complete calls to
sites that do not use
encryption
The system displays a
message stating that
encryption is required.
Your system is configured to require all calls to be
encrypted, and encryption is not available at the far
site.
Cannot dial remote system
in bonding calls. (The call
progress circles only show
blue or yellow.)
Switch protocol issue.
Start by calling the far site at 1x56 and progressively
try higher speeds, as appropriate. This will verify the
primary number.
Being able to dial non-bonded but unable to dial
bonded to all locations is usually a switch protocol
issue. Verify your ISDN provisioning with the
telephone service provider.
Dialing a remote site in
calls above some particular
speed does not work. (The
call progress circles do not
turn green, or remain blue.)
The far site may be unable
to accept calls above this
speed.
Go to the
Call Status
screen. Highlight the circle for
the channel dialed. The number dialed for the
channel will be displayed as you highlight the circle.
Make sure that the far site has entered the number
for its ISDN lines correctly.
Cannot select the desired
speeds for bonding calls
from the speed selection.
Speeds do not show when
selecting the speed icon.

Admin Settings > Network > Call
