	Notes:
		-before saving the file:
			-you should check the $_FILES['file']['error'] to check for specific issues
			-the file size should be also checked and rejected if too big ($_FILES['file']['size'])
			-you should not just blindly accept the file name sent by the client. normalize/sanitize the destination file name first ($_FILES["file"]["name"]) or generate a file name yourself		
		-you might check also the X- headers for call-id, caller, called or others (altrough these can be also part of the file name)
			foreach (getallheaders() as $name => $value)
			{
				if($name == 'X-callid')		
				{
					error_log("SIP CALL-ID:".$value\n", 0);
					break;
