RPC Timeout

For SmartClient_v3p_2013-01-04

We are using DMI.call to invoke a method on the server. There are cases where the call is taking a little over 4 minutes to return and we are getting a timeout. I read where the default value is 4 minutes for RPC requests. Is there a simple way to increase the timeout?

Here is the code and the bindings:

DMI.call("SurveyDetailsDMI", "SurveyDetailsDMI", "getSurveyDetails", pMap, "pumpData(data)");


<Application>
<rpcBindings>
<!-- Reporting DMI calls -->
<ServerObject ID="SurveyDetailsDMI" className="com.genesys.survey.reportingdmi.SurveyD etailsDMI">
<visibleMethods>
<method name="getSurveyDetailsHeader"/>
<method name="getSurveyDetails"/>
<method name="updateSurveySentiment"/>
<method name= "getSurveyNote"/>
<method name= "updateSurveyNote"/>
<method name= "getSurveyComment"/>
</visibleMethods>
</ServerObject>
</rpcBindings>
</Application>
