Resolution
Cisco CallManager Express provides an interface that enables simple one-to-one remote control of a Cisco IP phone by an associated PC that is running Cisco IOS Telephony Service Provider (TSP), a Telephony Application Programming Interface (TAPI) that supports the placing of outbound calls from an application phone address book.
This interface is intended to support only basic TAPI services to enable caller ID-based screen pop-ups for incoming calls and to support simple outgoing call placement using one-click, address book-style speed-dialing from the PC application.
Note: This service does not add full TAPI support for multiple users or the multiple call handling required to implement complex features like Automatic Call Distributor (ACD) or IP Contact Center (IPCC).
