I'm trying to send an MMS to openwave mm7 server using, not openwave mms sdk but only php and pear-soap extension. I am now at a point where I can't go further, if you have some links or some doc to help me or even help me to complete my php code: <? include("SOAP/Client.php"); $url = 'http://edev.openwave.com:8080/mm7'; $namespace= 'http://www.3gpp.org/ftp/Specs/archive/23_series/23.140/schema/REL-5-MM7-1-0'; $soapclient = new SOAP_Client($url,$namespace); $method = 'SubmitReq'; $params = array('MM7Version'=>'5.3.0', 'SenderIdentification'=>array( 'VASPID'=>'16179433222','VASID' =>'reicherV', 'SenderAddress'=>array('RFC2822Address'=>'test@test.com')), 'Recipients'=> array('To'=>array('Number'=>'1617433848')), 'MessageClass'=>'Personal','DeliveryReport'=>'false', 'ReadReply'=>'false','Priority'=>'Low', 'Subject'=>'Test SOAP mm7','ChargedParty'=>'Sender'); $soapheader = new SOAP_Header('{urn:http://schemas.xmlsoap.org/soap/envelope/}Header',NULL, array('TransactionID'=>'ID_1234','ContentType'=>'multipart/related', 'VASPID'=>'vasp','VASID'=>'vasp')); $soapclient->addHeader($soapheader); $response = $soapclient->call($method,$params,$namespace); print_r($response); ?> I get a soap_fault object (a big array) with the message: no operation SubmitReq in wsdl I tried a lot of different method names MM7_Submit ... nothing seems to work. I also tried with a nowsms test server, I have the same error. If somebody has some ideas, I'd be really happy. Thanks
