Problem Description Solutions
Dialing a Conference On Demand
fails.
Inviting other endpoints into a
conference using the CON service
fails.
The endpoint dials a CON service,
and the call is rejected because of
one of the following:
• The MCU is not registered or is
offline.
• The CMA system cannot log
into the MGC.
• The MGC has no resource
available for the call.
• The MGC’s IP address is not
entered in the CMA system.
• Check the diagnostics log for an
ARJ reason from this endpoint.
• Verify that the MCU is
registered with the CMA system
and is online.
• Verify that the MCU registered
with the CMA system has the
MCU’s IP address filled out in
the Devices list.
• Verify that the MCU login ID and
password for the CON service
are correct.
• Verify that the H.323 network
service that the MCU is using is
set as the default service.
• Verify that the MCU has enough
available resources to start this
conference.
• Verify that the CON service is
enabled. Go to Admin > Dial
Plan and Sites > Services.
