Point-to-Point Calling Problems and Solutions
Problem Description Solutions
ViewStation and ViaVideo
have an incorrect RAS IP
address.
These endpoints are configured with
a NAT address and may not receive
the RCF message from the
gatekeeper.
The endpoints need to be reconfigured to
disable NAT.
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 > Dial Plan and Sites >
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.
Dialing by IP address fails. A registered endpoint cannot call an
unregistered endpoint by IP address
within the same site.
A dialing rule is not enabled or is set
to block instead of route.
• Check the Reports > Gatekeeper
Message Log for error messages.
• Verify that the registered endpoint is
registered.
• Verify that the Deny calls to/from
unregistered endpoints check box is
cleared. Go to Admin > Gatekeeper
Settings > Primary Gatekeeper to
change this setting.
• Verify that the IP address dialing rule is
enabled and set to route.
