2、產(chǎn)力與在電話上花的小時(shí)數(shù)成反比。為了滿足雙方和那些在此之間的用戶的需要,我們期待一個(gè)統(tǒng)一的信息系統(tǒng)。 </p><p>  一度,UM簡(jiǎn)單意味著將電子郵件,傳真郵件和語音郵件放到一個(gè)郵箱進(jìn)行管理和操縱。 今天,我們通過電話用戶界面,根據(jù)一個(gè)用戶的操作,把更多的實(shí)時(shí)通信系統(tǒng),包括即時(shí)消息( IM ),現(xiàn)場(chǎng)管理和呼叫路由規(guī)則的使用集成在一起。這聽起來可能很繁瑣,但供應(yīng)商將這些功能分開出售,使您的組織可以選擇需要的部分

3、。 </p><p>  根據(jù)Radicati組織的調(diào)查,UC(統(tǒng)一通信)促成了企業(yè)的健康增長。支持融合技術(shù),如VoIP和SIP (會(huì)話發(fā)起協(xié)議),將促進(jìn)收益從2005年的4.69億美元增長到2009年的9.39億美元,其中包括PBX和電話供應(yīng)商,通訊軟件,語音系統(tǒng),甚至業(yè)務(wù)流程系統(tǒng)供應(yīng)商。 </p><p>  為了趕上這股浪潮,我們要求供應(yīng)商向我們提供他們的SIP兼容產(chǎn)品。我們希望每個(gè)

4、產(chǎn)品與開放原始碼的IP PBX在SIP的信令模式下工作并進(jìn)行測(cè)試。 我們的理論依據(jù)是PBX上購買已接近生命周期結(jié)束的Y2K進(jìn)行升級(jí),企業(yè)期待考慮能結(jié)合現(xiàn)有資源的IP PBX從而提升他們的電話系統(tǒng)。 這使得支持SIP的IP PBX成為一張熱門車票。SIP在終端使用更多的智能化處理,如IP電話和個(gè)人電腦,能迅速整合業(yè)務(wù)應(yīng)用,電子郵件服務(wù)器,目錄,甚至實(shí)時(shí)的UC申請(qǐng)。 此外,基于IP和SIP開放式標(biāo)準(zhǔn)的產(chǎn)品將縮短開發(fā)時(shí)間。 </p>

5、;<p>  我們還規(guī)定,產(chǎn)品必須支持一個(gè)通用電子郵件信箱,語音郵件和傳真;TTS (文本語音)被用來管理一個(gè)通用郵箱,并使用其它各種各樣的電子郵件協(xié)議,如IMAP, MAPI, POP3和SMTP ;和Active Directory或LDAP 。 我們希望能通過Outlook和網(wǎng)絡(luò)瀏覽器訪問通用信箱,并進(jìn)行網(wǎng)絡(luò)系統(tǒng)管理。 </p><p>  Interactive Intelligence,西

7、論的SIP對(duì)這個(gè)平臺(tái),還言之尚早。Mitel表示,其支持3300的ICP在我們的測(cè)試中缺乏競(jìng)爭(zhēng)力,而阿爾卡特拒絕參加,還聲稱其資金有限。 思科系統(tǒng)公司,愛立信,NEC,北電和Unisys都沒有回應(yīng)我們的邀請(qǐng)。</p><p>  我們的參與者提供了能綜合電子郵件,傳真郵件和語音郵件到一個(gè)郵件存儲(chǔ)的服務(wù)器,如Microsoft Exchange 2003 。 但是,一些公司已提出超越傳統(tǒng)UM的方案。Interact

8、ive Intelligence的communité和西門子的HiPath xpressions都在他們的軟件中包括了一些管理功能。 西門子的HiPath還支持SMS (短信服務(wù)) ,而communité支持即時(shí)通訊。3 Com公司提供了考勤管理,但他們不提供其考勤管理的IP模塊進(jìn)行評(píng)測(cè)。 </p><p><b>  在錫拉庫扎的麻煩</b></p>&l

9、t;p>  不幸的是, SIP的互操作性問題放慢了我們的測(cè)試。首先,我們的Asterisk服務(wù)器達(dá)不到要求,手機(jī)沒有響應(yīng)或線路忙。我們?yōu)榻鉀Q這個(gè)問題做了很多工作,我們建立Asterisk系統(tǒng)以外的專門的擴(kuò)展線路連接到這個(gè)服務(wù)器。另一個(gè)可行方案是配置IP電話進(jìn)行訪問。不過,這只是我們旅途的開始 。 </p><p>  一旦信息出現(xiàn)在這個(gè)系統(tǒng)中,他們需要以他們的方式回到Asterisk的路線。 舉例來說,我們

10、測(cè)試fmfm情景,其中,來電者會(huì)遍歷Asterisk網(wǎng)絡(luò)以訪問這個(gè)平臺(tái)。 一旦符合某一個(gè)規(guī)則,他們可能回到Asterisk。我們發(fā)現(xiàn)在該P(yáng)BX上, communité無法繞開試驗(yàn)處理提出的訪問中提到的SIP驗(yàn)證。 我們對(duì)Asterisk系統(tǒng)進(jìn)行驗(yàn)證,以進(jìn)行完整的測(cè)試。但保持啟用驗(yàn)證也有原因,例如對(duì)進(jìn)入Asterisk的語音郵件進(jìn)行限制和為用戶提供更多的擴(kuò)展機(jī)會(huì)。 </p><p>  所有參與方在這次測(cè)

11、評(píng)中被分開設(shè)計(jì)安裝和配置公用設(shè)施的系統(tǒng)資源,日常管理的職能,如管理用戶和配置郵件路由。 在大多數(shù)情況下,系統(tǒng)的資源分配只進(jìn)行一次,除非有一場(chǎng)災(zāi)難,收購或計(jì)劃搬遷。 無論是從產(chǎn)品的Interactive Intelligence和西門子有易于使用的系統(tǒng)配置工具 。3 Com的實(shí)用工具難以運(yùn)行在一個(gè)遠(yuǎn)程的X窗口,令人想起一個(gè)基于PBX的TDM命令行界面實(shí)用工具。 communité和HiPath雙方都有良好的圖形界面和資源分配。&

12、lt;/p><p>  我們對(duì)所有產(chǎn)品進(jìn)行了充分的測(cè)試。 在communité和HiPath中我們可以在水晶報(bào)表中以Excel和CSV格式導(dǎo)出報(bào)告。3 Com公司的IP通訊模塊提供了免費(fèi)的報(bào)告工具;我們的評(píng)測(cè)報(bào)告來自于Apprentice app和像他們的深度和廣度。 </p><p>  排除故障也并不困難。每個(gè)產(chǎn)品提供了具有全面的日志和追蹤功能的系統(tǒng)模塊。 Communit&#

14、方處理這些任務(wù)都一樣。 我們可以通過TUI聽電子郵件,在PC上看語音郵件。 但只有communité和的HiPath提供了一些模擬的語音識(shí)別語音指令。 我們?nèi)栽谄诖Z音-文本轉(zhuǎn)換方式的改善,所以我們可以閱讀我們的所有電子郵件。于是可能出現(xiàn)這種情況,我們的眼睛可能會(huì)很高興我們的耳朵正在幫忙。 </p><p>  它將使我付出什么? </p><p>  我們的費(fèi)用是,這個(gè)有100

15、接口可為1000用戶規(guī)模的企業(yè)服務(wù),假設(shè)只有小部分人將使用UM。 我們正確的,但語音信箱是緊緊包裹著這個(gè);所有這三個(gè)供應(yīng)商,包括與他們的這個(gè)語音服務(wù)器模塊,讓我們?cè)从谡Z音信箱或存儲(chǔ)后,拉它從另一個(gè)交換機(jī)或IP PBX的。 有關(guān)這個(gè)軟件,然后發(fā)送或復(fù)制到Lotus Domino。 因此,最后我們根據(jù)100個(gè)普通用戶和1000個(gè)語音郵件用戶進(jìn)行定價(jià)評(píng)估。這樣,企業(yè)會(huì)更具自身?xiàng)l件選擇實(shí)施UM。 </p><p>  所

16、有產(chǎn)品郵件都能準(zhǔn)確發(fā)送,但I(xiàn)nteractive Intelligence的communité由于其緊密的整合了Active Directory和Exchange,以微弱的優(yōu)勢(shì)擊敗了西門子公司的HiPath獲得了我們的編輯選擇獎(jiǎng)。 而且,由于SIP是本地化的,以communité ,即系統(tǒng)舉行了地面時(shí),與Asterisk體制進(jìn)行最好的整合。與其他產(chǎn)品一樣, communité的工作替代了我們的其它應(yīng)用。 &

17、lt;/p><p>  西門子的HiPath在性價(jià)比上排第二,但其連接器只支持基礎(chǔ)的整合與通訊。communité舍棄它短期的全面架構(gòu)從而升級(jí)為Active Directory 。 至于3 Com公司,在勞顧會(huì)期間,結(jié)合我國企業(yè)的資源和Asterisk服務(wù)器,它表示傾向于使用自己的IP電話模塊與它的IP通訊。 雖然IP的通訊模塊沒有工作,如果你為整個(gè)系統(tǒng)考慮預(yù)算想要去除這部分,可與3 Com公司商談。<

18、;/p><p>  communité升級(jí)而成的HiPath xpressions ,由于其優(yōu)越的系統(tǒng)和用戶管理界面,能方便的定制和配置我們的訊息。 </p><p>  Interactive Intelligence是一家軟件公司。 它可以提供communité 2.3.1光碟加載到我們的實(shí)驗(yàn)室一個(gè)測(cè)試服務(wù)器上。 但最近,該公司提供4,8,12,24接口的communi

20、戴爾的PowerEdge,我們制定了在其各自的Active Directory域。 然后一個(gè)Interactive Intelligence公司的工程師向我們發(fā)出一個(gè)可執(zhí)行文件,以擴(kuò)大我們的廣告模式,以容納communité 。 我們建立了一個(gè)域管理員。在Exchange 2003的系統(tǒng)中,此用戶有權(quán)利打開所有郵件,并作為用戶發(fā)送和接收郵件。 一旦我們完成安裝架構(gòu)的更新,我們的communité廣告用戶被添加到本地管

21、理員組,以啟動(dòng)和停止服務(wù)和協(xié)調(diào)郵件路由之間的communité系統(tǒng)和Exchange 2003 。 </p><p>  相對(duì)于競(jìng)爭(zhēng)對(duì)手, communité系統(tǒng)支持語音郵件和UM。 我們的“用戶”已通過Web瀏覽器進(jìn)入其語音信箱。 但不同于HiPath, communité只提供通過網(wǎng)絡(luò)收發(fā)語音郵件。 完全同步的的語音郵件被存儲(chǔ)到Exchange 2003服務(wù)器。 </p&g

22、t;<p>  用戶的語音郵件交付到Exchange Server 。 但也有人堅(jiān)持在communité的語音郵件的存儲(chǔ)可進(jìn)行時(shí)間的配置。 這提供了一些冗余。</p><p>  communité的安裝向?qū)秩菀椎膶⑺傻狡涓髯缘木W(wǎng)域。 安裝向?qū)槲覀兲峁┝私⒐芾碛脩舻哪_本,安裝許可證,建立一個(gè)初步的組織,設(shè)置一個(gè)撥號(hào)計(jì)劃,并選擇一個(gè)數(shù)據(jù)庫等功能。我們?yōu)檫M(jìn)行這項(xiàng)測(cè)評(píng)使用了

23、MSDE ( Microsoft數(shù)據(jù)引擎)。 該軟件還支持Microsoft SQL和Oracle數(shù)據(jù)庫,但這些都不包括在communité的許可之中。 </p><p>  之后,按照計(jì)劃,作為系統(tǒng)管理員我們把注意力放到 Win32應(yīng)用程序網(wǎng)站和系統(tǒng)資源配置。我們建立了一個(gè)組織,在邏輯上儲(chǔ)存的所有系統(tǒng)資源。 請(qǐng)注意,獨(dú)立和單獨(dú)的單位,可以創(chuàng)造多個(gè)組織或單獨(dú)的部門或地點(diǎn)的企業(yè)。 唯一的限制因素是人數(shù)受到

24、許可證的限制,服務(wù)器運(yùn)行communité進(jìn)程和用戶數(shù)量要得到Active Directory的支持。 communité的組織和用戶信息保存在Active Directory中。 雖然communité可以使用ADAM( Active Directory的應(yīng)用模式) ,在不需要Active Directory的應(yīng)用中,該模式不符合進(jìn)行這項(xiàng)測(cè)評(píng)的要求。 </p><p>  雖然西

25、門子的HiPath提供優(yōu)秀的基于LDAP的目錄和企業(yè)信息的存儲(chǔ)路徑一體化設(shè)計(jì),并提供完全的控制系統(tǒng)管理和配置,但得益于更緊密的整合與Active Directory和更直觀的管理工具,從而communité擊敗了其它對(duì)手。但是,即使排在第二,HiPath應(yīng)該根據(jù)其性價(jià)比,制定更低的售價(jià)。 </p><p>  在我們的實(shí)驗(yàn)室中,西門子公司有信心使其軟件運(yùn)行在基于英特爾的硬件的Windows Server

26、 2000或2003服務(wù)器之上 。 他們證明他們的論點(diǎn)是通過安裝一個(gè)“黑匣子” ,結(jié)合它與Active Directory域和我們的SIP的啟用Asterisk的PBX ,使Exchange Server 2003作為統(tǒng)一的信息存儲(chǔ)。 </p><p>  為了測(cè)試,我們將HiPath安裝在運(yùn)行于雙處理器的Intel Xeon ( 3.0千兆赫)服務(wù)器與3 GB的RAM的Windows 2003 Advanced

27、 Server之上 。 輕松實(shí)現(xiàn)了西門子公司建議的平臺(tái)2003服務(wù)器( 1英特爾piii , 1 GHz的處理器與1024 MB的RAM ) 。 西門子建議增加物理內(nèi)存兩倍大小的虛擬內(nèi)存。 </p><p>  安裝之前,我們禁止的非法用戶登錄支持SMTP的Windows 。 西門子提供自己的網(wǎng)絡(luò)服務(wù)器,網(wǎng)絡(luò)的APL (接入?yún)f(xié)議層)和SMTP的進(jìn)程信息-日程,然后重試安裝,這對(duì)一區(qū)(域控制器) ,需要支持SMTP

28、的Windows。 一旦有了這些先決條件,在一臺(tái)服務(wù)器上使用CD進(jìn)行安裝,并配置所有的HiPath組件,這需要417 MB的磁盤空間。 注意HiPath組件可以分布在多個(gè)服務(wù)器的,以提高性能。 </p><p>  HiPath的組成部分包括Windows附帶的Win32服務(wù)和基于Web的應(yīng)用程序和命令行管理操作界面。 服務(wù)器組件分為兩類:內(nèi)核組件和API的部件。 HiPath的內(nèi)核包括四個(gè)組成部分: 1個(gè)MTA

29、 (郵件傳輸代理) ,一個(gè)專有的數(shù)據(jù)庫( infostore ) , 1個(gè)延長訊息Reporter服務(wù)和一個(gè)名稱定位尋找資源。 </p><p>  進(jìn)入內(nèi)核組件是由API的整合與共同對(duì)外協(xié)議,如SMTP和HTTP ,并提供申請(qǐng)管理員和客戶端。 此外, HiPath組成部分,西門子使用Scansoft的speechify 3.0供其TTS引擎,以通過Exchange郵件存儲(chǔ)或信箱閱讀電子郵件和傳真郵件標(biāo)題。 信箱

30、是西門子存放語音信息的倉庫。 在我們的測(cè)試中,我們使用信箱從我們的Asterisk體制接收語音郵件,并與我們的Exchange Server同步。信箱是用來作為雙郵件存儲(chǔ)同步之間的交流與電訊為一個(gè)完全冗余系統(tǒng)。 在活動(dòng)的交流,這個(gè)可以繼續(xù)從電訊箱。 </p><p>  3 Com公司的IP通訊模塊落后與競(jìng)爭(zhēng)對(duì)手,主要是因?yàn)槠銩ctive Directory和Exchange 薄弱的整合。 雖然我們可以使用Exc

32、個(gè)專門的TTS引擎。 IBM的x系列306 eServer服務(wù)器可以處理多達(dá)150個(gè)端口(同時(shí)用戶) 。 客戶還可以使用IBM公司的eServer 346從而處理250個(gè)端口。 </p><p>  該vcxs分別為動(dòng)力的GNU的Linux (內(nèi)核2.4.21 )和保護(hù)的防火墻的基礎(chǔ)上iptables的。 和一樣,都communité和的HiPath ,它與Web功能的系統(tǒng)管理。 但之前,我們得到在那

52、were ready and willing, and sent systems to our Syracuse University Real-World Labs®. But a large number of vendors have not moved down the SIP path for unified messaging at all or weren't far enough along to qu

57、IP interoperability problems slowed our testing. First, our Asterisk server wouldn't forward a request to the UM servers when phones were not answered or lines were busy. We worked around this by setting up dedicated

58、 extensions to route outside the Asterisk system to the UM servers. Another workaround was to do forward access in the IP phone's configuration. But that was only the start of our travails.</p><p>  Once

59、 messages were in the UM system, they needed to route their way back to the Asterisk. For example, we tested FMFM scenarios in which callers would traverse the Asterisk network to the UM platform. Once there, a rule migh

60、t send them back to an extension in Asterisk. We found that the PBXs under test handled the forward-access reference in SIP, but Communité couldn't get around SIP authentication.</p><p>  We turned

61、authentication off on the Asterisk system to complete testing. But there are reasons to keep authentication enabled, such as restricting access to Asterisk's voicemail and giving users more access to extensions.</

65、 in Crystal Reports, Excel and CSV formats. 3Com's IP Messaging Module offers a free reporting tool; we reviewed the reports available from this Apprentice app and liked their depth and breadth.</p><p> 

66、 Troubleshooting wasn't difficult. Each product provided extensive logging and full trace capabilities by system module. Communité went well beyond that, though, with its Interaction Designer graphical applicati

67、on generator, which we used to customize and troubleshoot message and event processing. Siemens' HiPath included its King Lear simulation tool that let us send messages (e-mail, fax and voice) through the system for

68、testing and quality analysis. </p><p>  Next we integrated each product with our Active Directory and Exchange servers, then routed messages from the Asterisk system to the product's UM platforms and del

69、ivered faxes from our Faxbox Face-saver to Exchange message stores. All the participants handled these UM tasks like champs. We could listen to e-mail over the TUI and see voicemail on the PC. But only Communité and

71、cing is difficult to measure. We asked for the cost of 100 UM seats for a 1,000-user enterprise, under the assumption that only a subset of people would be using UM. We were correct, but voicemail is tightly wrapped with

72、 UM; all three vendors included with their UM servers voicemail modules that let us originate voicemail or store it after pulling it from another PBX or IP PBX. The UM software then sent or copied it to the UM store--Exc

73、hange or Lotus Domino, for example.</p><p>  When all the messages fell into place, Interactive Intelligence's Communité edged out Siemens' HiPath for our Editor's Choice award, thanks to it

74、s tight integration with Active Directory and Exchange. And, because SIP is native to Communité, that system held its ground the best when integrating with the Asterisk system. The workarounds we applied with Commun

75、ité worked with the other products as well.</p><p>  Siemens' HiPath came in at a good price and a close second, but its Connector-based integration with Exchange left it short of Communité'

79、 productivity is inversely proportional to on-phone hours. To satisfy the needs of both groups and those in between, look to a unified messaging system. </p><p>  At one time, UM simply meant putting e-mail,

80、 fax messages and voicemail into one message store for management and manipulation. Today, UM is incorporating more real-time communication systems, including instant messaging (IM) and presence management, and using cal

81、l-routing rules to find and follow a person if he or she is not available from one TUI (telephone user interface). That may sound like a lot to manage, but vendors sell UM functionality separately, so your organization c

84、p>  To catch this wave early, we asked vendors to send us their SIP-compliant UM products. For our tests, we wanted each product to work with the open-source IP PBX Asterisk in SIP-signaling mode. Our rationale is tha

85、t PBXs purchased for Y2K upgrades are nearing end of life, and enterprises looking to upgrade their phone systems will be considering IP PBXs that integrate with existing resources. That makes SIP-supported IP PBXs a hot

89、Edge Server (Intel PIII, 997 MHz) with 640 MB of RAM and Communité installed. It also came with sufficient HMP (Host Media Processing) resources for SIP</p><p>  Note that Intel recently added a softwar

92、to accommodate Communité. We created a Domain Administrator (User=Communité AD) to install the schema update. This user also had rights to open all messages and send and receive messages as a user in the Exchan
