Registration Problems and Solutions
Problem Description Solutions
Unable to place calls to an
MCU conference room
from a registered Polycom
HDX system
The dynamic management mode
RealPresence Resource Manager
system rejects the ARQ stating
that the “endpoint is not
registered” to the gatekeeper
even though the system indicates
it is registered.
• The MCU is not registered to the
gatekeeper
Some endpoints are not
assigned ISDN numbers.
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.
• Verify that the endpoint belongs to the
site that has assigned ISDN number
ranges. To do so, go to Admin >
Topology > Sites and make sure the
site has the correct ISDN range
specified in the ISDN Number
Assignment pane.
• 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.
Endpoints that were
previously registered and
auto-assigned ISDN
numbers are being
rejected when attempting
to register.
Inconsistent configuration in ISDN
number assignment has occurred.
• Verify that the previous ISDN range
was changed.
When the RealPresence
Resource Manager system
is restarted, some
registrants that were
previously online are now
offline.
Some endpoints do not reregister
when the RealPresence Resource
Manager system goes down.
Some MCUs do not reregister
automatically after two retries.
• Reboot the MCU.
