3 Cisco AVVID System Architecture
Distributed Manageable Adaptive Open Applications TAPI, JTAPI, SMDI Cisco Unity Cisco IPCC Call Admission, Call Routing Call Processing Directory CallManager Gateway Router Switch Infrastructure Cisco IOS® Network Services Cisco AVVID Architecture slide - displays the classic 3 layers of bearer channel processing in the infrastructure layer, the processing layer denoting Call Manager, and the Application layer where Contact Center and Unified Messaging reside. The key messages are: Applications are physically independent from Call processing and physical voice processing infrastructure, that is they may reside anywhere within your network Call processing is physically independent from the infrastructure thus you can have a call manager in Chicago processing call control for a bearer channel in San Francisco The Infrastructure can support multiple client types, hard phone, soft phone, and in the future video... Clients PC IP Phone Video SoftPhone Wireless

21 Cisco IP SoftPhone 1.3 IP SoftPhone caveots If using NT security, requires NT domain win 95,98 requires print and file sharing to be on Avvid directory-based security early test cycle- does not require either. Call Initiation Users will be able to initiate calls in many ways: Double-click on a directory entry. Drag a directory entry onto a “line block” (area of the dialog representing a line appearance). Select an address from a drop-down list of recently dialed addresses (redial). Start typing in the upper text field of an idle call block and press Enter or hit the "Dial" button. Addresses will not be limited to E.164 format; any address that is valid in the AVVID will be allowed. Call Reception User’s should be able to answer calls manually by hitting a shortcut key combination , clicking on a button on the screen or making a collocated phone device go off-hook. They should also be able to configure the SoftPhone to automatically answer the phone. When the SoftPhone is in Standalone mode, the user should be able to select a customized greeting recorded in an audio file to be played to the caller upon going off-hook. Caller ID Since the time a call is being offered, all Caller ID information will be displayed for the call. This information will include caller address (phone number), name and number dialed. Call Deflection The user will be able to “deflect” a call to voice mail or to another destination while the call is being offered to him/her. A list of the most recently used destinations used for deflecting will be available for the user to choose from. Windows-based IP Phone client for Cisco CallManager Take your work extension with you on the road, even if connected with VPN client over the Internet

34 Schedule a Conference Simple Menu Options One page Conference Setup
Hide conference for Privacy Schedule Recurring Conferences This is the Add Conference screen. Notice the simplicity. Note the Repeat Options. A conference owner (e.g. the individual who sets-up the conference) may choose to either allow a conference to be seen by others as a part of the scheduled conference listing or if privacy is a concern these can be hidden. Hidden conferences are also kept hidden on the Cisco IP Phone Services key from all but the conference owner. If a conference is not hidden, it is viewable by all who subscribe to the Cisco Conference Connection Service.

35 Cisco Conference Connection
Audio conference server with web-based scheduler Dial in to single number Cisco IP phone services conference entry User accounts synchronized with CallManager LDAP directory profiles Supports up to 100 ports Cisco Conference Connection is a meet-me audio conference server for scheduled conferences. Audio conferencing increases the effectiveness of meetings. Participants may reside in distant locations or be traveling. Location is no longer an impediment to effective meetings. This reduces travel time and costs and provides for better and faster decisions. All this is done while minimizing the disruption to individual schedules. Even within a single corporate campus, participants can increase their efficiency frequently participating in meetings from their desk. Specialized applications include:service calls, field sales, training, corporate announcements (internal and external) Conference owners use an intuitive web interface to schedule calls. Conference participants dial into a single number, enter a meeting ID and are then joined into the conference. Cisco IP Phone Services may also be configured so users can enter a conference at the touch of a button from their IP Phone. Cisco Conference Connection supports up to 100 ports. Ports may be divided among any number of participants. All may be in one large conference call or multiple smaller conferences may be planned. The number of ports required is application dependent. However, one standard guage is to assume one conferencing port is required for every 20 phones (includes phones in conference rooms, reception areas, etc.) Cisco Conference Connection is IP based and integrates with CallManager. Yet as with Cisco IP Phones, conference participants need not be IP based. Connectivity is universal. Cisco Conference Connection user accounts are synchronized from CallManager which uses LDAP directory profiles. Offered as an option on a dedicated Cisco MCS , MCS or Compaq DL320 and DL380.

36 Cisco Unity Communications Solutions
Cisco Unity Voice Messaging IP Voice Messaging Upgradeable to Unity Unified Messaging Supports Cisco CallManager and/or several legacy PBX integrations Cisco Unity Unified Messaging Full-featured Unified Messaging (UM) solution Supports Cisco CallManager and/or several legacy PBX integrations Compatible with MS Exchange 5.5 & 2000 Will be compatible with Lotus Domino Cisco Personal Assistant Personalized call routing rules with call screening and “follow-me” Speech enabled voic access, name dialing, and ad hoc conferencing IP Phone Productivity Services for access to calendar, , voice mail, & contacts It is easiest to break down the Cisco Unity product line into voice messaging solutions and unified messaging solutions.

37 Cisco Unity ViewMail for Outlook Delivers
Talk about the unified access to messages. Again emphasize on UM. If you have a demo this is a great place to do it! Leverages what users already know Compose , voice, and fax, from a single interface Forward voice with text, text with voice

38 Cisco Personal Assistant 1.3 Enhanced Productivity
Route calls by user-defined rules Time of day Calendar Who the caller is Forward calls to user-defined phone numbers Single number Series of numbers (i.e., office, mobile, or home) Follow me (forward all calls now) Screen calls Select which calls to accept in real time Routing MS Exchange 5.5 and Exchange 2000 are the two supported calendars. Other calendars will be added in the future. Categorize your callers into groups, like a “buddy list.” Highest priority always goes to cellular phone. Another group might always go to voic . Tell PA what series of numbers to which to forward calls PA will call the designated first number, if the user doesn’t pick up after a specified number of seconds, PA will try the 2nd number, etc. A user might have a group of regular numbers that includes office, cellular phone, home office. A user might have a second group of contact numbers that includes a remote office number and hotel number. User can specify phone numbers, voic , pager Call PA and say “follow me” – PA will forward calls to the phone the user is on. The user can also specify another “follow me” number and number of days to forward. Call Screening Plays spoken names from corporate directory Plays phone number of outside callers Outside callers with blocked caller IDs are asked to state their names

39 Cisco Personal Assistant 1.3 User Web Administration
What days do I want to run my rules? The look and feel of the user administration screens follows CallManager standards and incorporates feedback from usability studies. This administration page is used to decide what rule-sets should be applied. In the screen capture, the user has activated a rule-set for regular workdays and a different for working remotely on Thursday. The user has also activated a “vacation” rule-set for a date range. Rule-sets activated for a date range take precedence over rule-sets activated for days of the week.

40 Cisco Personal Assistant 1.3 IP Phone Productivity Services
Log in to any IP Phone* in CallManager cluster for access From any desk, co-worker’s office, conference room, or lobby phone Login using same user ID and password/PIN as CallManager, Extension Mobility, Unity *Cisco IP Phone models 7940 and 7960

41 Cisco Personal Assistant 1.3 More IP Phone Productivity Services
MailView Access and Cisco Unity voice mail from any IP Phone in the cluster Contacts Synchronization Synchronize personal address book with existing contact lists MailView Access all and voice messages within Inbox Voice mails from Exchange Server streamed from Web server to IP Phone IP Phone Services Web server uses the same mechanism as an client on a PC or the PA server to access the message store. Through PC synchronization, PDAs can display the same information but can only be updated when actually docked or otherwise connected to the network. Contacts Synchronization Synchronize personal address book stored in LDAP directory with contact lists in Exchange Server. Synchronize personal address book with MS Outlook clients on PC using synch application available with Cisco CallManager 3.1+ When PDA syncs with PC, it also obtains Personal Contact entries. Rule-set Activator Activate Personal Assistant rules from IP phone, web interface, or via speech recognition Apply rules to specific days or date range Rule-set Activator For call routing rules
