          SIP OPTIONS Ping
        </h3>
        <p>The SIP OPTIONS Ping feature can be enabled
          on the SIP Profile associated with a SIP trunk to dynamically
          track the state of the trunk's destination(s). When this
          feature is enabled, each node running the trunk's SIP daemon
          will periodically send an OPTIONS Request to each of the
          trunk's destination IP addresses to determine its reachability
          and will send calls only to reachable nodes. <b>A destination
            address is considered to be "out of service" if it fails to
            respond to an OPTIONS Request, if it sends a Service
            Unavailable (503) response or Request Timeout (408)
            response, or if a TCP connection cannot be established. </b>
          The trunk state is considered to be "in service" when at least
          one node receives a response (other than a 408 or 503) from a
          least one destination address. SIP trunk nodes can send
          OPTIONS Requests to the trunk's configured destination IP
          addresses or to the resolved IP addresses of the trunk's DNS
          SRV entry. Enabling SIP OPTIONS Ping is recommended for all
          SIP trunks because it allows Unified CM to dynamically track
          trunk state rather than determining trunk state on a per-call
          and timeout basis.
