Description (partial)

Symptoms: In an H323 IP-to-IP Gateway (IPIPGW), during call setup when the
 OLC-ACK is received after the connect message, the call is not completed and
 the return OLC-ACK is not forwarded by the IPIPGW. The issue is sporadic and
 does not occur all the time.
 Conditions: This has been observed on a IPIPGW running Cisco IOS Release
 12.4(20)T1-ES, having an H323 on both sides of the gateway. This only happens
 when the connect message is received before OLC-ACK exchange between the 
 parties is complete.
