Point-to-Point Calling Problems and Solutions
MCU and Gateway Dialing Problems and Solutions
Problem Description Solutions
A call with an alias as the
dial string from a registered
endpoint cannot be placed
to another registered
endpoint. The two
endpoints are in different
sites.
• The site link between the sites
in which the endpoints reside is
not correctly defined or is
missing.
• No bandwidth is available to
the site link.
• The calling bit rate is higher
than the bit rate defined in the
site link.
• ISDN alternate routing is not
available.
• Dialing rules may not be
enabled or may be set to block
instead of route.
• Go to Admin > Topology > Site Links
and make sure that a site link exists
between the two networks.
• Make sure that the IP addresses of
both endpoints are included in their
respective sites.
• If site topology is defined for both
endpoints, verify that there is enough
bandwidth in the site links between
the two sites.
• Verify that the dialing bit rate is lower
or equal to that of the maximum bit
rate defined for the site links.
• If the endpoint is ISDN capable, verify
that the ISDN parameter is correct.
Problem Description Solutions
Call fails when using an
MCU service.
Dialing an MCU service
results in a network error.
The call using the MCU service is
rejected because of one of the
following:
• The MCU is not registered.
• The MCU is offline.
• The MCU prefix is not
registered as an E.164 alias.
• The MCU resource issue was
sent through resource
allocation indication or
resource allocation.
• Verify that the MCU is registered.
• Verify that the MCU is online. If the
device is offline, reboot it.
