Cannot dial remote system
in BONDING 384 K calls.
(The call progress circles
only show blue or yellow.) Switch protocol issue. Start by calling the far site at 1x56, 1x64, 2x56, or
2x64K, as appropriate. This will verify the primary
number. If these calls complete, try 256K, then 384K.
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
after the first channel
connects.) The far site may be unable
to accept calls above this
speed. Go to the Call Status screen. Highlight each of the
circles for each of the channels dialed. The number
dialed for each channel will be displayed as you
highlight the corresponding circle. Make sure that the
far site has entered the number for each of its ISDN
lines correctly.
The numbers for Line 1 - Line 4 should correspond to
connections 1 - 4 on the Quad BRI network interface
module.
Lower the number of lines to dial in parallel.
Cannot select the desired
speeds for BONDING calls
from the speed selection. Speeds do not show when
selecting the speed icon. 1. Go to Admin Settings > Network > Call
Preference and select
four times to go to
the Call Speeds screen.
2. Select the desired call speeds.
Multipoint calls downspeed
when a voice-only call is
added. This is normal. No action is necessary.
Voice-only calls cannot be
placed using a set-top VSX
system. This is normal. Place voice-only calls using the
SoundStation VTX 1000 conference phone.
Voice-only calls cannot be
placed using a VSX 7000e
or VSX 8000 system. The system might not have
a good connection to a
phone line. Use a telephone to verify that there is a dial tone on
the line connected to the input on the VSX system.
Hanging up the
SoundStation VTX 1000
conference phone does not
end the video call. This is normal. Use the SoundStation VTX 1000 conference phone
END VIDEO soft key or the VSX system remote
control to end video calls.
Call streaming to the Web
does not work. You may be attempting to
stream to a different subnet
and the router is not set to
allow multicasting. Make sure the network is configured to allow
multicast streaming. To send a stream across a
subnet, enable multicasting on the network or unicast
to a particular IP address, which will forward the
stream to that IP address regardless of the location
destination.
You can also test this feature by directing the stream
to a specific computer that uses Apple QuickTime as
a streaming player.
