iPower Collaboration System Tips and Troubleshooting
54
Problem
The call connects at less than the
requested rate; the system displays
"Call connected at <rate>"
Corrective Action
• Operationally test the lines for making
outgoing calls. Perform the following steps:
1. Call a known good number. If the call
connects at the requested rate, all lines
work.
2. After the call connects, check the call rate
from the Conference Statistics screen.
- If the call connected at 512, all lines work.
- If some lines do not come up, the lines
may not be connected to the network
properly.
• Verify that the ISDN lines are connected and
active. Perform the following steps:
1. From the Hardware Diagnostics
application, click Test ISDN Lines. If a line
does not reach the active state, make sure
that it is connected properly. See the
iPower installation documentation for
information about how to connect ISDN
lines.
2. If all ISDN lines activate, close the
Hardware Diagnostics application and start
the Collaboration application.
3. If you still have call problems and your
switch type is DMS100, NI1, 5ESS G3, or
5ESS Multipoint, you may have a problem
registering your SPIDs with the network.
From the Operating Statistics application,
check your ISDN configuration or contact
your network provider.
