Asynchronious momentaly response handling with soap response

Hello,

I am testing Asynchronious SOAP testcases.
Mechanism is:
I execute SOAP request and wait for SOAP response on port/path, and verify against some assertions.

But for some testcases and for negative-testcases where response comes momentaly - it is not possible to catch them, because the response is too fast.

What solution can be used (something like to start listening before executing testcase)?

P.S. Without groovy scripts.

Regards.
