Resolving Peer-to-Peer Call Failure

ALL FAILURE
This section describes what to do if peer-to-peer calls (both IP-to-ISDN and
ISDN-to-IP calls) fail to connect.
Note In this section we assume that the LAN endpoint is an H.323 endpoint.
Possible Causes Verification Steps
One of the peers does not exist. Check that the peer is configured in the
peer list at Gateway > Settings> IP
Connectivity.
Ports configuration mismatch. In the peer list at Gateway > Settings> IP
Connectivity, check that:
 The LAN endpoint is configured
with the correct signaling port
number.
 The Gateway Q.931 port is
identical to the port configured in
the Gateway (using the Advanced
Commands).
The wrong dial plan is in use—the
destination number does not begin with a
Gateway service.
Change the destination number.
If the problem is not resolved, contact
RADVISION Customer Support.
Provide the following information to
RADVISION Customer Support:
 Gateway traces with level 6.
 H.323 stack log.
