Response service associated with consumer web service descriptor is not getting invoked

What product/components do you use and which version/fix level?

webMethods 9.10

What are trying to achieve? Please descibe in detail.

We are calling an end system through SOAP webservice.
We have a requirement to process asynchronous SOAP responses.
At the time of creating a consumer web service descriptor, Integration Server has created the responseService folder.
We are using wM9.10 version.
In responseService folder , 1 response service and 1 genericFault_Response service is created.
IS is supposed to invoke these services for processing SOAP responses received for the associated consumer web service descriptor.
We have attached WS-Addressing policy to the web service.

Do you get any error messages? Please provide a full error message screenshot and log file.

When I am testing,the response service is not getting invoked.
For every call ,genericFault_Response service is getting invoked, as IS is not able to determine the specific response service.

We are passing below parameters while calling the response service.

EndpointURL – taken from response endpoint address template.
WSA:Action – is set to the name of response service.

Any thoughts on how to resolve this issue.
