I managed to find a solution in the meantime: using the xhttp module + uac gives a perfect solution.

There is no need for an associated SUBSCRIBE request in such a case. ON// Our requirement is, that if a specific event happens on the server side, I want to send an event to the client. My first idea is to use SIP NOTIFY, but perhaps a SIP MESSAGE could do the job as well. The client is registered over TLS, if necessary it could even subscribe for the event. What would you recommend, using the websockets? Or creating a module from the scratch?
