4. Cisco Unified Presence Solutions Multiple options to integrate presence: Cisco Unified Communications Manager Presence Speed-dial presence Call history presence Presence policy Cisco Unified Presence Server User status information Cisco IP Phone Messenger application Cisco Unified Personal Communicator Third-Party Presence Server Integration

5. Cisco Unified Communications ManagerPresence Characteristics Natively supported by Cisco Unified Communications Manager Allows an interested party (a watcher) to monitor the real-time status of a directory number (a presence entity) Watcher subscribes to status information of the presence entity Watcher can show the status of a presence entity using: Presence-enabled speed dials Presence-enabled lists (call and directory lists) Three possible states of watched directory number: Entity is unregistered Entity is registered—on-hook Entity is registered—off-hook

6. Cisco Unified Communications ManagerPresence Operation Off-hook 3. Information about Bryan’s phone is sent to John’s phone 2. Bryan’s phone goes off-hook Line 5697 is busy 4. John’s phone shows Bryan’s phone in off-hook state 1. John has subscribed for status of Bryan’s phone

8. Cisco Unified Communications ManagerSupport for Presence Directory numbers (lines) of Cisco IP phones can be watched By Cisco IP phones By SIP devices through a SIP trunk Directory numbers (lines) of Cisco IP phones, and endpoints that are reached via SIP trunks, can be watched by the following: Cisco IP phones SIP devices through a SIP trunk

9. Watching Presence Status on Cisco IP Phones Presence status can be seen on speed-dial buttons, call lists and directories.

11. Presence Configuration

12. Cisco Unified Communications ManagerPresence Configuration Procedure To enable presence-enabled speed dials: Customize phone button templates to include presence-enabled speed-dial buttons Apply phone button templates to phones Configure presence-enabled speed-dial buttons Apply subscribe CSS to phones To enable presence-enabled call lists: Enable the BLF For Call Lists enterprise parameter To allow presence subscriptions through SIP trunks: Enable Cisco Unified Communications ManagerPresence on SIP trunks

13. Step 1: Customizing Phone Button Templates Device > Device Settings > Phone Button Template Configure presence-enabled speed-dial buttons in phone button template

14. Step 2: Applying the Phone Button Template to IP Phones Device > Phone Assign phone button template to phone

15. Step 3: Configuring Presence-Enabled Speed Dial Buttons Device > Phone At the phone configuration page, click links to add a presence-enabled speed dial. Enter presence-enabled speed-dial configuration: presence entity to watch and label to be displayed on phone

16. Enabling Presence-Enabled Call Lists System > Enterprise Parameters Enable presence-enabled call lists

17. Enabling Presence on SIP Trunks System > Security Profile > SIP Trunk Security Profile Assign SIP Trunk Security Profile to SIP Trunk Device > Trunk Configure SIP Trunk Security Profile for presence Configure SIP Trunk Security Profile for presence

18. Presence Policies

19. Limiting Presence Visibility Cisco Unified Communications Manager Presence offers different ways to limit visibility of presence information: Presence-enabled speed dials Are statically configuredby Cisco Unified Communications Manager Administrator (cannot be configured by users) Subscribe Calling Search Space and (standard) partitions Presence-enabled call and directory lists Subscribe Calling Search Space and (standard) partitions Presence groups

20. Subscribe CSS and Partitions Separate CSSsare applied for calling privileges and presence: the (standard) CSS for calling privileges and a subscribe CSS for presence. A subscribe CSS is applied to a watcher: a SIP trunk, a phone, or an end user. The subscribe CSS determines which presence entities a watcher is allowed to monitor. Similar to with traditional CSSs, a presence entity can only be watched if the watcher has the presence entity’s partition in its subscribe calling search space. The (standard) partition that is applied to a line or a route pattern referring to a trunk is used for both calling privileges and presence. If no partition is applied to a line or route pattern, it is available to all watchers.

21. Subscribe CSS and Partition Considerations Presence policies and calling privileges share some configuration settings: Partitions on lines and route patterns Implementing presence policies impacts calling privileges and vice versa Any changes to partition configuration affects calling privileges (standard CSSs) and presence policies (subscribe CSSs) Design and implementation of calling privileges and presence policies have to be performed together!

22. Subscribe CSS and Partition Considerations – Sample Scenario Baseline configuration does not include any partitions (no calling privileges and no presence policies are in place). If partitions and (standard) CSSs are implemented for calling privileges, subscriptions will fail: Lines and route patterns now have partitions. Devices (phones and trunks) do not have subscribe CSSs If partitions and subscribe calling search spaces are implemented for presence policies, calls will fail: Lines and route patterns now have partitions. Devices (phones, lines, and trunks) do not have CSSs.

23. Presence Policy Example – Subscribe CSS Calling Search Spaces:C-1: P-1, P-2 C-2: P-1, P-2, P-3 C-3: P-1 Route Pattern: 8.1003 Partition: P-3 SIP Trunk: Subscribe CSS: C-3 Presence Group: G-3 (CSS) Phone1 1003 Line: 1001 Partition: P-1 Presence Group: G-1 (CSS) SIP Phone3 Phone2 Line: 1002 Partition: P-2 Presence Group: G-2 (CSS) Effective Permissions: Phone1 to 1002: permitted Phone1 to 1003: denied Phone2 to 1001: permitted Phone2 to 1003: permitted Phone3 to 1001: permitted Phone3 to 1002: denied Phone1: Presence Group: G-2 Subscribe CSS: C-1 (CSS) Phone2: Presence Group: G-2 Subscribe CSS: C-2 (CSS)

24. Presence Groups Presence groups can be used to implement presence policies: Watchers and presence entities are put into presence groups. Subscriptions are permitted within presence groups. Subscriptions can be allowed or denied between presence groups. Permission can be configured independently for each direction IP phones have separate presence groups. Line presence group (presence entity) Phone presence group (watcher) SIP trunks have only one presence group. used for both watcher and presence entity Presence groups only apply to presence-enabled call lists – they do not apply to presence-enabled speed dials

25. Presence Policy Example – Presence Groups Presence Groups: G-2 to G-3 permitted G-3 to G-1 permitted Rest denied Route Pattern: 8.1003 Partition: P-3 SIP Trunk: Subscribe CSS: C-3 Presence Group: G-3 (CSS) Phone1 1003 Line: 1001 Partition: P-1 Presence Group: G-1 (CSS) SIP Phone3 Phone2 Line: 1002 Partition: P-2 Presence Group: G-2 (CSS) Effective Permissions: Phone1 to 1002: permitted Phone1 to 1003: permitted Phone2 to 1001: denied Phone2 to 1003: permitted Phone3 to 1001: permitted Phone3 to 1002: denied Phone1: Presence Group: G-2 Subscribe CSS: C-1 (CSS) Phone2: Presence Group: G-2 Subscribe CSS: C-2 (CSS)

26. Interaction of Presence Groups and Partitions and Subscribe CSSs Presence groups, partitions, and subscribe CSSs can be combined. Both have to permit subscription for successful watching Provides 2 levels of hierarchy – useful in larger deployments Example: Requirements: No subscriptions are allowed across departments. Within a department, managers can only be watched by their assistants. Solution: Use one presence group per department. Deny inter-presence group subscriptions. Include manager partition only in the subscribe CSS of their assistant.

27. Presence Policy Configuration

28. Unified CM Presence Policies Configuration Procedure To implement presence policies based on partitions and CSSs: Configure partitions and CSSs Assign partitions to lines and route patterns Assign subscribe CSSs to phones and trunks To implement presence policies based on presence groups: Configure presence groups Set the default inter-presence group policy Assign presence groups to lines, phones, and SIP trunks

29. Step 3: Assigning Subscribe Calling Search Spaces to Phones and SIP Trunks Apply Subscribe CSS to trunks and phones Apply Subscribe CSS to trunks and phones Device > Phone Device > Trunk

30. Step 1: Configuring Presence Groups Enter Name and Description for presence group System > Presence Group Individually configured permission towards listed presence group Permission to unlisted presence groups is determined by service parameter For individual configuration towards another presence group, select destination presence group and select type of permission For individual configuration, select presence group and set permission for subscriptions towards selected presence group

31. Step 2: Setting the Default Inter-Presence Group Policy The Default Inter-Presence Group Subscription specifies the system default for presence subscriptions towards presence groups for which no explicit permission has been configured. System > Service Parameter (Cisco CallManager) Set the Default Inter-Presence Group Subscription

32. Step 3a: Assigning Presence Groups to Lines and Phones Device > Phone Assign presence group to phone (in subscriber role) Call Routing > Directory Number Assign presence group to directory number (in presence entity role)

33. Step 3b: Assigning a Presence Group to a SIP Trunk Device > Trunk Assign presence group to SIP trunk Same presence group is used in subscriber and presence entity role The presence group configured on a SIP trunk applies to both subscriptions being sent out and being received on the trunk.

34. Summary Cisco Unified Communications ManagerPresence allows lines or endpoints reachable through SIP trunks to be monitored for their status (on-hook versus off-hook). Most IP phones support presence-enabled speed dials; type B Cisco IP phones using SIP also support presence-enabled call and directory lists. Cisco Unified Communications ManagerPresence configuration includes implementing presence-enabled speed dials and enabling presence-enabled call and directory lists. Cisco Unified Presence policies can be applied for controlling presence subscriptions. Cisco Unified Communications ManagerPresence policy configuration includes implementing partitions and subscribe calling spaces and presence groups.
