Corrective Action
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.
• From the Operating Statistics application,
check the gatekeeper configuration.
• Notify the network administrator.
• Place LAN calls using IP addresses that do
not require a gatekeeper.
• From the Configuration Summary category of
the Operating Statistics application, check the
local phone numbers.
• Run the ISDN Bit Error Rate Test. This test
allows you to place a call from one line to
another in order to verify line integrity.
Select Start>Programs>Polycom iPower>
Administrator>Network Test. If a line
connects, then the line is good.
• Check the phone number, system name, or
TCP/IP address to make sure that you are
dialing a videoconferencing system.
• Redial the call as "restricted".
• Double-click the
Statistics icon on the taskbar in the lower
right-hand corner of the screen. Check the
report and the far-end data.
• Remain in the call at the reduced rate. The
call is operating at the maximum rate
supported by the far end.
A single-BRI system provides 1x128
maximum and a Quad-BRI system
Note
provides 1x512 maximum.
