思科统一用户界面:TUI, GUI, VUI

Cisco Unity和Cisco Unity Connections有三种不同的用户界面。这些接口通常被称为TUI、GUI和VUI。TUI代表电话用户界面，代表通过电话上的按钮(1-9，*和#)可用的选项。TUI接口导致了传统电话中的双音多频数字(DTMF)。通过IP语音转发数字，被称为dtmf中继。在Cisco H.323或SIP网关上配置的VoIP拨号对等体中，缺省情况下没有开启DTMF-Relay机制。通过IP基础设施通过语音实现DTMF数字有多种方法，但它们可以概括为带外(OOB)或带内(IB)。DTMF数字转发OOB在信令协议(SCCP、SIP、H.323或MGCP)中发送，而不是在实时协议(RTP)媒体流中发送，尽管呼叫(信令)已经建立。转发的带(IB)数字DTMF在RTP媒体流中使用RTP报头中的特殊payload-type identification (PTI)标识符发送。Cisco Type A电话不支持带DTMF中继转发。 Additional information on DTMF Relay can be found in one of my earlier blogs. The TUI interface is the traditional mechanism in which end users have worked with the voicemail system. The Unity system prompts are presented to the user. By dialing the 1 button on the DTMF pad of the phone, the end user has the ability to listen to their voicemail. Links to the standard conversation TUI documentation appears in the references section at the end fo this blog. Cisco has alternate TUI interfaces that can be loaded to emulate alternative voicemail solutions. This is very useful if Cisco Unity is being used to replace an existing voicemail solution. Cisco Unity includes various graphical user interfaces (GUI) depending on the licensed features used in Cisco Unity. Cisco Unity includes a component where end users can access their voicemail from a web based interface referred to as the Cisco Unity Inbox (UI). The Unity Inbox is a class of service (CoS) controlled, licensed feature in Unity which allows mobile workers to access their voicemail over a web interface. The Cisco Unity Inbox is a great option for voice mail only deployments with mobile workers who need access to their voicemails. The Unity Inbox is not frequently used in environments that have licensed the unified messaging (UM) features of Cisco Unity. Environments running unified messaging use a client utility for Microsoft Outlook of IBM Lotus Notes. The view mail for Outlook (VMO) or view mail for Notes (VMN) client loads a media master control in the messaging client which allows users to listen to and record voice mails in their E-Mail client without loading another application. Cisco Unity Connection 7.0 also supports the VMO and VMN clients. Voice recognition is a new new feature of Cisco Unity 7.0. Voice recognition is very CPU intensive. Cisco recommends dedicating at least one server to voice recognition if this feature will be accessed by many end users (subscribers). The voice commands used in Cisco Unity voice recognition is referred to as the voice user interface (VUI).
