sipKeepAliveMethod

Sip Keep-Alive Method
          
Method used to perform the SIP Keep-Alive. The Keep-Alive
mechanism generates an activity between the SIP gateway and
the remote end. If the mechanism is unable to reach the remote
end, the SIP gateway is disconnected.
          
  * None: No Keep-Alive is performed.
  * SipOptions: SIP OPTIONS are sent periodically for each
    gateway to the corresponding server. Any response received
    from the server means that it is reachable. No additional
    processing is performed on the response. If no response is
    received after the retransmission timer expires
    (configurable via the InteropTransmissionTimeout
    parameter), the gateway considers the server as
    unreachable. In this case, any call attempt through the
    gateway is refused. SIP OPTIONS are still sent when the
    server is unreachable and as soon as it becomes reachable
    again, new calls are allowed.
  * Ping: A Ping is sent periodically for each gateway to the
    corresponding server. The response received from the
    server means that it is reachable. If no response is
    received after the retransmission timer expires
    (sipTransmissionTimeout), the gateway considers the server
    as unreachable. In this case, any call attempt through the
    gateway is refused. The Pings are still sent when the
    server is unreachable and as soon as it becomes reachable
    again, new calls are allowed.
  * TcpKeepAlive: For TCP and TLS connections, a small
    Keep-Alive packet is periodically sent to probe an idle
    connection. The connection is terminated if the remote end
    failed to reply after a few retries, configurable through
    the SipEp.SipKeepAliveRetry parameter. The delay between
    two Keep-Alive transmissions is configurable with the
    SipEp.SipKeepAliveInterval parameter.
          
Note: The SipOptions and Ping methods are only available for
Trunk gateways, See the Gateway.Type parameter.
