Solution: The H.323 call setup timeout can be tuned using the h225 timeout tcp establish
voice class configuration command:
voice class h323 1
h225 timeout tcp establish <value 0 to 30 seconds>
dial-peer voice 919 voip
application session
destination-pattern 919555....
voice-class codec 1

OSP Problem Isolation
If you are having trouble isolating the problems that are occurring with settlement, try the
following:
Check the originating and terminating gateway configurations for dial peers,
settlement providers, and certificates.
Check the network between the originating gateway, terminating gateway, and the
server. Ping each device to make sure that the machines are running.
Verify that IP calls can be made successfully. If so, the problem is specific to
settlement.
Use the debug voip ivr settlement EXEC command on the originating gateway to see
if the TCL IVR script initiates a settlement request to the server.
Use the debug voip settlement network EXEC command on the originating gateway
to capture the HTTP requests sent to the server and the response from the server. If
the originating gateway gets no response from the server, contact the settlement
provider.
Use the debug voip settlement misc EXEC command to see the list of TGWs
returned from the server. If this list is incorrect, contact the settlement provider.
If the terminating gateway rejects the settlement token because it’s too soon or too late
to use it, synchronize the terminating gateway clock with the server.
OSP Clearinghouse Configuration Examples
This section shows two examples:
Configuring OSP on the originating gateway
Configuring OSP on the terminating gateway
OSP Clearinghouse Configuration Examples 469
Configuring OSP on the Originating Gateway
Example 10-20 shows an originating gateway configured to register with an OSP server.
NOTE The first tuplet in each IP address in this example has been replaced with a unique variable.
