NodePing Elixir v1.1.4 NodePing.Checktypes.Sip View Source
NodePing's SIP monitoring can verify that your SIP server is responding to new requests. The check does not initiate a call, but rather tests that the the server accepts a SIP connection by sending the OPTIONS command and watching for the response. Even if your server does not support the OPTIONS command and returns an error, this indicates that the server is up and operating, so the check succeeds.
