HOW do I send OCSP Stapled response from SIP Server?

I was implementing OCSP stapling support for one of my SIP applications. I was able to fetch the OCSP response and send it to SIP client from SIP Application. This verfies the server behavior of my SIP application.

But to verify the client behaviour of my SIP application, I was unable to find a SIP server which sends the OCSP stapled response to my SIP Application.

So I would like to know if there are any SIP tools which readily support supports OCSP stapling so that I can test the client behavior of my SIP Application.
