Client integration: You can connect Cisco Unified CME with Microsoft CRM and Salesforce.com using Telephony Application Programming Interface (TAPI) Windows driver based on Cisco IOS Software TSP.
Server integration: You can connect Cisco Unified CME with third-party applications using the Cisco Unified Communications Express Services Interface API. This API enables protocol interaction between Cisco Unified CME and third-party applications to perform CTI functions, including call monitoring, call control, and call provisioning with any SCCP device registered with the Cisco Unified CME. It includes two elements: embedded CTI protocol support within Cisco Unified CME and Java Function Library (referred to as the “UC Express Services SDK”) that co-resides on an external server with the third-party application. This API can support either co-located or service provider-hosted application deployment scenarios. For more information, please refer to: http://developer.cisco.com/web/ucxapi/home.
