今天是我自2000年來Cisco筆試第二次的fail紀錄(上一次是 DCN，這一次是CIPT2)，現在voice的筆試有很多需要強記的觀念及步驟，今天就遇到一題要求我將所有的指令依序排列(內容完全跟課本中某個slide完全相同)，但是我實在沒有什麼機會作lab因為不熟練所以沒有得分。另外一題則是觀念問題，要我把Mobility Connect 以及 Mobile Voice Access步驟選出來，這也是完全要考驗考生對Lab的實作能力，但是這部份的內容在課本說得並不清楚，所以我在這邊把CIPT2 Lab中的步驟大綱點出來，方便各位快速查詢： Mobile Connect Task 1: Add the Mobility Softkey to IP Phones a. Configure a Softkey Template with the Mobility Softkey b. Assign the Softkey Template to the IP Phone Task 2: Associate an End User Account with the IP Phone and Enable the Use of Mobility a. Configure an End User for Device Mobility b. Configure the Office Phone to be Owned by the End User Task 3: Configure Remote Destination Profiles and Remote Destinations a. Configure a Remote Destination Profile b. Configure a Remote Destination Mobile Voice Access Task 4: Enable Cisco Unified Mobile Voice Access a. Activate the Cisco Unified Mobile Voice Access Service b. Configure Cisco Unified Mobility Service Parameters c. Configure End Users ...

以下是讓IP Phone註冊到Cisco Call Manager Express最基本的指令。其中有一行非常重要的指令就是 create cnf-files 。如果沒有這個指令，當IP Phone嘗試去註冊到CME時，CME將不會建立xml檔案來發放給IP Phone。這個問題在我之前嘗試要連到TP新加坡Remote Lab時就遇過了，VPN確定通了但是IP Phone就是無法完成註冊，結果請新加坡那邊的負責Remote Lab 的同事協助查了很久還是找不到問題，後來幸好有Chris Yang幫忙，終於找到Remote Lab HQ Router(CME)上缺少了這個config才把這個問題給解決。不過很奇怪的是…經過了幾個月之後，這個星期又請公司admin幫忙再跟新加坡借了一次CVOICE Remote Lab，結果有問題的initial config到現在還是有問題，唉，同時是華人，怎麼台灣跟新加坡的華人工作態度卻是大大不同。 telephony-service max-ephones 2 max-dn 2 ip source-address 172.16.1.1 port 2000 create cnf-files ! ! ephone-dn 1 number 1001 ! ! ephone 1 button 1:1

(USOC Wiring Diagram) Telephone wiring for a phone outlet is typically either 1, 2 or 3 pairs (2, 4, or 6 conductor). Most cable nowadays is UTP (unshielded twisted pair). There may be instances where you may need to connect to or transpose from the old "quad" cable. The diagram below provides the transposition between these standards. Pair 1 (T1 & R1) Usually the primary dial tone or talk circuit is wired to the center two pins (pins 3 & 4) and is the white/blue and blue/white pair (AKA: T1 & R1 - tip 1 and ring 1). A standard single line phone draws dial tone from these center pins. NOTE: The type of wiring shown here is known as USOC (pronounced U-sock). See background below. Pair 2 (T2 & R2) The secondary circuit is wired to the two pins (pins 2 & 5) directly to the side of the center pins and is the white/orange and orange/white pair (AKA: T2 & R2 - tip 2 and ring 2). Depending on the application, the secondary circuit can either be t...

1. 將網路線中斷 (如果不是使用Power Over Ethernet的話，請把電源線移除) 2. 按著 # 鍵不放 3. 接上網路線 (如果使用額外電源變壓器請重新接上電源線) 4. 等待IP Phone畫面出現 “Reset to factoy defaults” 提示 5. 放開 # 鍵並且依序按下以下電話按鍵 123456789*0# 6. 完成IP Phone重設動作

Intra-Cluster Communication Signaling (ICCS), which provides the communications with the Cisco CallManager Service process that is at the heart of the call processing in each server or node within the cluster. The intra-cluster traffic between the servers consists of the following: Database traffic from the IBM Informix Dynamic Server (IDS) database that provides the main configuration information. The IDS database is replicated from the publisher server to all other servers in the cluster using best-effort. The IDS traffic may be re-prioritized in line with Cisco QoS recommendations to a higher priority data service (for example, IP Precedence 1 if required by the particular business needs). An example of this is extensive use of Extension Mobility, which relies on IDS database configuration. Firewall management traffic, which is used to authenticate the subscribers to the publisher to access the publisher's database. The management traffic flows between all servers in a cluster....

Shared Line Appearances: SLAs allow you to place a call on hold at one set and pick it up easily at another set. SLA is also known as SCA: Shared Call Appearance. You can join an existing conversation be pressing the corresponding line button. Typically the phones will have dedicated buttons with LEDs for each of the shared lines. Bridged Line Appearance: BLA allows multiple devices to share a single directory number.
