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.
