Polycom ReadiManager SE200 Operator's Guide
Problem
An endpoint shows the
gatekeeper is not registered
in the Registration Status
field of the Device
Information Detail View.
The RadVision OnLAN
MCU continually changes
state: from online to offline
and offline to online.
Some endpoints are not
assigned ISDN numbers.
Endpoints that were
previously registered and
auto-assigned ISDN
numbers are being rejected
when attempting to register.
When ReadiManager is
restarted, some registrants
that were previously online
are now offline.
7–6
Description
ReadiManager receives the RRQ
message, but not the LWRRQ
message from this endpoint.
The endpoint did not send a
LWRRQ message within the offline
timeout period specified in the
Administrator View > System Setup
> Gatekeeper Settings screen.
The Radvision OnLAN MCU ignores
the RCF Time to Live (TTL) field,
which is filled in with the value that
the Administrator specified in the
offline timeout field in the
Administrator View > System Setup
> Registration Settings screen.
A registered H.323-only system was
not assigned an ISDN number. The
system could belong to a network
that does not have ISDN number
ranges assigned to it.
No ISDN numbers are available to
assign.
Inconsistent configuration in ISDN
number assignment has occurred.
Some endpoints do not reregister
when ReadiManager goes down.
Some MCUs do not reregister
automatically after two retries.
Solutions
• Reboot the endpoint.
• Set the TTL field to 195 in
ReadiManager or reconfigure the
Radvision OnLAN MCU to send the
registration requests in the same time
period specified in ReadiManager.
• Add the MCU manually.
• Reboot the MCU to force registration to
occur.
• Verify that the endpoint belongs to the
site that has assigned ISDN number
ranges. To do so, go to Administrator
View > Dial Plan Setup > Sites and
make sure the site has the correct ISDN
range specified in the ISDN Number
Assignment screen.
• Verify that ISDN numbers are available
to assign.
• Verify that the RCF message "Can't find
ISDN free pool" from the gatekeeper
returns to the endpoint.
• Verify that the previous ISDN range was
changed.
• Reboot the MCU.
