VX Extended UC Features

UC功能


VX with Extended UC Features

• Extended functionality to enable the removal of the Mediation server requirement between OCS and the VX gateway 可代替媒介伺服器

• Brings added benefit including: 提供功能 No separate Mediation Server HW required - reduced H/W maintenance costs 節省硬體

Single Mgmt interface (Reduces provisioning, installation, and management costs) 節省安裝、管理成本

Supports multiple SIP trunks & TDM trunks (supports additional codecs ex G729) 支援一點對多點系統

Lower Audio delay (one less transcode & one less jitter buffer)減少語音延遲和抖動

RTAudio embedded - Better audio quality on LAN (Versus G.711) 直接支援RT-Audio

G.711 can be used for lower latency可使用G711

Full High Availability configuration with LQM and redundant routing.提供全面支援

Upgrade option for Extended UC Features (for VX Basic G/W) 不同容量系統

• Brings Mediation server functionality within VX 內置媒介伺服器 Media Relay Authentication service 提供媒體流轉發/論證

Multipart SDP 直接支援SDP

Gateway insert‘s itself into AD 目錄服務AD分享

RT Audio (narrowband) 支持RT-Audio

Siren直接支援Siren語音Codec

Media NAT/Firewall traversal (ICE draft 6/19)穿透防火牆

QOE support支持QOE

NET Basic Gateway Benefits, NET方案優點

• Integrate Microsoft UC/UM with several PBX/IP-PBX

同時相容UC/UM

• Both Upstream and Downstream model相容雙向implementations available per customer choice

• Consolidates voice-mail, fax, and speech with

Exchange UM 內置全部UM功能

• Only Gateway with AD/LDAP based call control

唯一產品提供基於AD/LDAP路由

Basic Gateway Architecture Drawbacks 問題

• Needs a separate Mediation Server 需要媒介伺服器

• Additional costs: $3K server per branch

office + Regular maintenance

• Additional delay introduced in

transcoding to RTA轉換Codec增加延遲

Permanent Circuits / MRD Circuits

專線


Permanent Circuits / MRD Circuits 專線

• Two new CAS signaling Protocols supported on VX: 最新CAS信令支持

• CAS Permanent Circuit

– Permanent Circuits established across SIP or BSP, and actively monitored. 經過IP傳送

– Signaling Transported end to end using RFC 2833

• CAS abcd bit changes，直流信號傳送

• DTMF or MFR1 digits

– Circuits ‘always open’ but with bandwidth only consumed during conversation.

通道永遠接通，資訊傳送才佔用頻寬

• CAS MRD Protocol (Manual Ring Down)

– CAS ‘wink’ used to establish call to SIP end point. 直接傳送“Wink”

– SIP ‘Info’ messages used to ‘refresh’ call or alert remote party on subsequent ‘wink’使用SIP 資訊包傳送 “Wink”

– Can terminate CAS MRD circuit to any SIP device, CAS信令直接控制SIP終端


VX CAS Permanent Circuits – ‘Tunneling’隧道方式

• Provides support for devices with proprietary ABCD signaling

直接傳送ABCD直流信號– eg. Dealer boards

• Calls are established at boot-up and maintained with active circuit

monitoring. 直接控制

• ABCD bits are relayed using RFC2833,使用RFC2833協議包傳送– SIP and BSP transport protocols can be used

Single Number FAX

傳真和電話同號


Single Number FAX

• Solution to provide true ‘single number reach’ for users. 每個用戶一號

• Reduced DDI number ranges for users節省號碼資源– No need for separate FAX number for every user 不需要分配每個使用者單獨傳真

號

– Every User can receive BOTH telephone calls and FAX messages toSAME number

• Integrated with Active Directory for seamless integration to Exchange無縫整合AD / UM– User information obtained and populated for Exchange Mailbox access

• Call diverted to Exchange for Fax delivery without ringing users number.傳真呼叫直接轉往Exchange Server

• Solution for both OCS and PBX users – true flexibility相容全網用戶

• Caller unaware of call interception for FAX detection 傳真呼叫不影響使用者


Enabling the single phone number – FAX services 傳真和電話同號

VX or Tenor

ISDN

Exchange

1. Call arrives from PSTN for John Smith

2. VX monitors call, and listens for CNG Tones (FAX)

3. Caller is sent ringing tone to maintain call progress (Unaware of Monitoring)

4. If no CNG tone detected, call is routed to OCS or PBX accordingly

5. If CNG tone IS detected, VX interrogates AD cache to obtain user

information for dialed number.

6. VX Diverts call to Exchange EUM server, correctly populating diversion

header with user information obtained from AD.

7. Exchange answers, T38 FAX is negotiated, and FAX is delivered directly to

users mailbox.

IVR & API Scripting Support

互動語音和二次開發介面


IVR and API Scripting Language互動語音和二次開發介面

• VXscript is the programming language a VX uses to define interactive call response behavior.使用Vxscript 程式設計互動語音介面

• VXscript provides functions for database access for retrieving useful information such as: 直接從資料庫獲得資訊

• Calling card parameters, Customer balances 電話卡號、使用者餘額

• Rate information for placing calls 費率表

• User preferences 使用者狀態

• Call routing for LCR decisions 成本路由

• VX IVR scripts can also be programmed to: 增加功能

• Receive information from a caller in the format of DTMF 接收DTMF

• Play or record audio recordings to/from the caller對主叫放音\錄音

• Using Scripting with IVR, VX can become fully engaged with the call setup, both for signaling, and Audio interception. 整個流程控制


IVR and API Scripting Language互動語音和二次開發介面

• VXscript syntax looks a lot like the C programming language 近似C 語言

• Fully Integrated with Active Directory, AD based lookups can be performed from within any part of the script. 直接AD分享

• Can interact with back-end Databases for queries, authentication and billing.直接獲得資料庫資訊

• Many examples of IVR functionality within Enterprise Case Studies……提供“樣品”程式
