Description (partial)

need to set tcp_keepalive_interval


HSI uses the default tcp_keepalive_interval of Solaris , which is 2 hours .

If a network firewall is deployed between HSI and other H323 GW or endpoints, and firewall may be set max idle duration less than 2 hours for TCP connections.
This will teardown a call when its connected duration reaches 2 hours.
To keep H323 TCP connections alive under this situation,  set tcp_keepalive_interval value of Solaris  is required.
