Integration Basics


Integration of DOTS Phone Exchange 2 into user applications is generally a straightforward process. For common programming platforms, such as ASP, ASP.NET, ColdFusion, PHP, etc., Service Objects will likely have sample code available online:
https://www.serviceobjects.com/developers/sample-code/phone-exchange

If the code you seek is not available online, you can ask Service Objects to build a custom example for you. Email support@serviceobjects.com for more details.


Web Service Structure

Web services provide a standard interface to encapsulate tricky business logic. They allow simple integration of applications via the web. Service Objects has followed web services best practices and come up with some of its own standards to ensure that its web services are as easy to integrate and as accessible as possible.


The host path or physical location of the web service is here:
https://trial.serviceobjects.com/pe2/web.svc


The location of the WSDL, or Web Service Definition Language document, is here (This is also accessible via the "Service Definition" link on the web service page.):
https://trial.serviceobjects.com/pe2/soap.svc?wsdl


Test Page
https://trial.serviceobjects.com/pe2/


Important Note!
SOAP is done via POST, only with special XML markup in the post-body


The WSDL is an XML document that defines the interaction web service, meaning its inputs, outputs, operations, and the like. Most likely, you will have another tool read this WSDL and make the operations available to you in your application via some type of proxy class. Whenever your utilities or IDE asks for a WSDL path, you can provide this one.

Every web service has operations that it offers to subscribers. These operations, also called methods, contain different functionality and return different outputs. DOTS Phone Exchange 2 has one operation, it will be described in detail later in this document.
