CISCO WebDialer API error, The AXIS engine could not find a target service to invoke what could be the problem?

Question

SOAP

Good afternoon.
I'm trying to deal with the CISCO WebDialer API.
I send to the address

https://SERVER:PORT/webdialer/services/WebdialerSoapService70

next query:

<?xml version="1.0" encoding="utf-8" ?> 
 <soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:WD70">
    <soapenv:Header/>
    <soapenv:Body>
       <urn:makeCallSoap soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
          <in0 xsi:type="urn:Credential">
             <userID xsi:type="xsd:string">user******</userID>
             <password xsi:type="xsd:string">pass*****</password>
          </in0>
          <in1 xsi:type="soapenc:string" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">1234</in1>
          <in2 xsi:type="urn:UserProfile">
             <user xsi:type="xsd:string">wd</user>
             <deviceName xsi:type="xsd:string">SEP001558C8970F</deviceName>
             <lineNumber xsi:type="xsd:string">901234565</lineNumber>
             <supportEM xsi:type="xsd:boolean">false</supportEM>
             <locale xsi:type="xsd:string">English</locale>
             <dontAutoClose xsi:type="xsd:boolean">false</dontAutoClose>
             <dontShowCallConf xsi:type="xsd:boolean">true</dontShowCallConf>
          </in2>
       </urn:makeCallSoap>
    </soapenv:Body>
 </soapenv:Envelope>

And in response I get:

The AXIS engine could not find a target service to invoke!  targetService is WebdialerSoapService70

When I try to go to the address through the browser:

https://SERVER:PORT/webdialer/services/WebdialerSoapService70

The following is output:

AXIS error
No service is available at this URL

What could be the problem? Am I creating the SOAP request incorrectly, or is the service just not running?
Thank you very much!
