(continued on next page)
Corrective Action
• Perform those tasks specified in the error
message. For example:
- Check the dialed number.
- Redial the call as "restricted".
- Ask the far end to call you.
- Redial the call later.
- Verify that the far-end system is working.
- Contact the network provider.
A No ISDN Channel message may
indicate a problem with the ISDN lines
Note
between your system and the
network.
• 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 the 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.
• Make sure that the number being dialed is
correct and properly formatted and try the call
again. Callers may need to dial 9 or include a
long distance access code or country code.
• Verify that the far-end system is in working
order.
Telephone the far-end site and find out if the
system is turned on and is functioning
properly.
