思科统一用户界面：TUI，GUI，VUI

思科统一和Cisco Unity连接有三种不同的用户界面。该接口通常被称为TUI，GUI，VUI和。TUI代表的电话用户界面和代表通过电话（1-9，*和＃）上的按钮可用的选项。的TUI界面导致的双音多频数字（DTMF）在传统的电话。转发在IP语音的数字，被称为DTMF继电器。DTMF继电器机制不是默认在思科H.323或SIP网关配置的VoIP拨号对等体开启。有超过语音IP基础设施的多种方式来DTMF数字，但它们可以被概括为带外（OOB）或带内（IB）。DTMF数字转发OOB在信令协议（SCCP，SIP，H.323，MGCP或），而不是实时协议（RTP）媒体流中被发送，尽管呼叫建立（信令）已经发生。DTMF在带内（IB）的数字转发在RTP媒体发送在RTP报头中使用特殊的有效载荷类型标识（PTI）标识符流。思科A型手机不带内DTMF中继转发支持。 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).
