After you install, enable, and configure Unified Messaging (UM) on a computer that is running Microsoft Exchange Server 2007, you can use the Exchange UM Test Phone application (ExchangeUMTestPhone.exe) to help you test the overall operation and functionality of the Exchange 2007 computer that has the Unified Messaging server role installed. You can use these tests to isolate problems that occur or to help you troubleshoot Unified Messaging.

The Exchange UM Test Phone application is a software-based telephone (softphone) application that is designed to interface with the Realtime Communication (RTC) media and Session Initiation Protocol (SIP) stacks on a Unified Messaging server. The Exchange UM Test Phone application simulates a telephone call, but the call is placed from a client computer that uses SIP and Realtime Transport Protocol (RTP) instead of from a telephone. You can use the calls placed to the Unified Messaging server to test the functionality of the Unified Messaging server without deploying or configuring an IP gateway or a Private Branch eXchange (PBX).

Getting Started with the Exchange UM Test Phone

There are multiple setup steps that you must complete before you run the Exchange UM Test Phone application and test a Unified Messaging server. This topic describes how to use the UM Test Phone to test Exchange 2007 Unified Messaging features. For more information about how to set up and configure the Exchange UM Test Phone, see the following topics:

Unified Messaging Feature Testing

There are three UM operational modes or features available in Unified Messaging that you can test by using the Exchange UM Test Phone: call answering, subscriber access, and auto attendant. For more information about the tests that you can perform when you use the Exchange UM Test Phone, see the following topics:

Debugging a Unified Messaging Server with the UM Test Phone

You can use the Exchange UM Test Phone application to debug a Unified Messaging server. When you debug a Unified Messaging server, you must prevent Microsoft .NET from optimizing the binaries during the just-in-time (JIT) process. For more information about how to prevent .NET from optimizing the binaries during the JIT process, see How to Debug Unified Messaging with the Unified Messaging Test Phone.
