No account needed.
Setup steps: Monitor a UDP service
In the address, write the host and the UDP port: "192.168.1.20:5060". The port is required.
To check that the service really answers, fill in "Datagram to send" and "Expected reply".
Without an expected reply, the check only fails when the host answers that the port is closed.
Heads-up. UDP has no connection: without an expected reply, a firewall that silently drops the datagrams looks healthy.
