After Clicking on a Cisco WebDialer-Enabled Number from a Web Page, Users Get a Chance to Confirm the Number Before Placing the Call.
With the prevalence of both internal and external Web-based directories available to enterprises, there is a strong need for a robust and simple integration with users' phones that lacks the complexity and price tag of traditional computer-telephony-integration (CTI) solutions.
Dialing external numbers, especially those that are long distance or that require access codes, is an error-prone process using a traditional phone keypad. The regular use of mobile phones with their built-in directories has made users less adept at memorizing and dialing long digit strings and more inclined to scroll through a directory to choose a phone number or click on a link from a Web page to place a call.
There is no need for administrators to manage CTI links or build Java Telephony Application Programming Interface (JTAPI) or TAPI applications, because Cisco WebDialer provides a simplified Web application and HTTP or Simple Objects Access Protocol (SOAP) interface for those who want to provide their own user interface and authentication mechanisms. Either way, the solution scales to support the entire Cisco CallManager cluster with full redundancy (refer to Figure 2).
Cisco WebDialer—Enabling an Existing Web-Based Directory Is a Simple Matter of Wrapping Phone Numbers with the Proper Code to Invoke the Web Service on a Cisco CallManager Cluster.
- Cisco WebDialer has a simple user interface to dial numbers from any Cisco WebDialer-enabled directory.
- Cisco WebDialer offers a scalable and redundant Web service; all users in a Cisco CallManager cluster can use Cisco WebDialer.
- A SOAP- or HTML-based application programming interface (API) provides for quick customization of the user interface or authentication.
- Web Service Definition Language (WSDL) for Cisco WebDialer is available on Cisco.com. WSDL provides a language for describing the messaging contracts between client and server as well as a format for describing web services. It defines an interface that can be used to automate code generation.
- Users of the Cisco CallManager can use the search function in their Directory (a search of user pages or user-pages directory search) to find directory phone numbers and simply point and click to dial that number.
