This chapter covers the following topics:
In addition to the voice mail and automated attendant (AA) applications discussed in Chapters 9, 10, and 11, Cisco CallManager Express (CME) can provide even more capabilities by integrating with external applications offered by Cisco and other vendors. This chapter briefly reviews the external applications that you can integrate with Cisco CME, such as applications that use the Telephony Application Programming Interface (TAPI) and Extensible Markup Language (XML) interfaces.
Some external applications integrate with Cisco CME by using Skinny Client Control Protocol (SCCP) connections. This chapter does not discuss these application because they appear to Cisco CME as IP phones (SCCP endpoints) and not as an application using an application interface, such as TAPI or XML. SCCP applications register with Cisco CME as IP phones do and communicate with the Cisco CME call processing features via SCCP messages as any IP phone would. Applications in this category include softphone PC applications such as the Cisco IP Communicator and IP Blue Software Solutions' softphone.
