Registration Problems and Solutions

Problem
When the gatekeeper
registration is set to auto-
discovery, endpoints do not
register.
An endpoint cannot register
with ReadiManager.
Endpoints cannot register
with ReadiManager.
The MCU (or MGC) cannot
register with ReadiManager.
• Conference On Demand Problems and Solutions
Some recommended solutions require access to screens in the
ReadiManager Administrator View. The default Operator permissions
do not provide access to this view. See the ReadiManager
Administrator to access the information you need.
Description
When auto-discovery is used, a
GRQ message is broadcast and
sent over multicast. However,
ReadiManager must be able to
receive one of these messages and
does not respond to this message if
it is not the default gatekeeper.
The endpoint is configured to use
ReadiManager as its gatekeeper,
but is being rejected during
registration.
In the gatekeeper diagnostic log, an
error has occurred during the
RRQ/RCF process that caused the
registration to fail.
An endpoint cannot register with
ReadiManager, but the gatekeeper
diagnostics do not indicate a
problem.
The gatekeeper sent the RCF
message, but the endpoint did not
receive it.
Some MCU vendors register with a
GRQ message instead of an RRQ
message.
Some MCU vendors do not retry
registration after a first attempt has
failed.
Solutions
• Verify that the Default Gatekeeper
check box is selected in the
Administrator View > System Setup >
Gatekeeper Settings screen.
• Verify that a UDP broadcast from the
endpoint's network can reach
ReadiManager, or that multicast is
enabled on all routers between the
endpoint and ReadiManager.
• Review the gatekeeper diagnostic logs
for the RRQ attempt by the endpoint
and determine the RRJ reason.
• Verify that the endpoint alias is not a
duplicate of other endpoint aliases.
• Verify that the endpoint does not have
NAT enabled.
• Verify that enough licenses remain.
• Verify that the IP address that the
gatekeeper sent to the endpoint is
correct.
• Verify that the Default Gatekeeper
check box is selected in the
Administrator View > System Setup >
Gatekeeper Settings screen.
• Reset the MCU or MGC card to force
registration to occur.
