how to associate a call to a case or potential

Hi There

I am trying to associate a call to a case using Zoho API method insertRecords:

https://crm.zoho.com/crm/private/xml/Calls/insertRecords?authtoken=***&newFormat=1&scope=crmapi&xmlData=

<Calls>

<FL val="Subject">subject</FL>

<FL val="Call Type">Inbound</FL>

<FL val="Call Purpose">Soporte</FL>

<FL val="SEMODULE">Cases</FL>

<FL val="Description">description callId:1</FL>

<FL val="Call Result">Successful</FL>

</row>

</Calls>

The application returned me the message:

 
  <response uri="/crm/private/xml/Calls/insertRecords">
 

 
     <result>
    
      <message> 
      Record(s) added successfully 
      </message>
     
        <recorddetail>
       
         <FL val="Id"> 
         770493000005582003 
         </FL>
        
         <FL val="Created Time"> 
         2014-12-24 09:12:22 
         </FL>
        
         <FL val="Modified Time"> 
         2014-12-24 09:12:22 
         </FL>
        
           <FL val="Created By">
          
            <![CDATA[ Tecnologia ]]>
           
           </FL>
          
           <FL val="Modified By">
          
            <![CDATA[ Tecnologia ]]>
           
           </FL>
          
        </recorddetail>
       
     </result>

 
  </response>
 

 
 But I can see the call associated at case when I go to https://crm.zoho.com/crm/EntityInfo.do?module=Cases&id=770493000005546287

 
 I verified that the case id exist using the method https://crm.zoho.com/crm/private/xml/Cases/getSearchRecordsByPDC?newFormat=1&authtoken=***&scope=crmapi&selectColumns=All&searchColumn=caseid&searchValue=770493000005546287

 
 Exist another method to associate a call to a case using the API?

 
 Thanks
