Configuring Presence for Communication Manager Express

Presence is a real-time indicator of user availability that’s often integrated with a Cisco Unified Communication (UC) cluster. It integrates with calendaring, location, and workflow systems, allowing users to automatically share their status with others. Presence resides on a single or multiple servers depending on the number of users you want to provide presence capabilities for.

Presence is usually integrated with Cisco’s Commnication Manager which provides the call control for a UC cluster. Typically, Communication Managers are used in larger deployments when there are 300 or more phones. However, Presence features aren’t just for deployments that include a CUCM and Presence, it can also be incorporated in a Cisco Communication Manager Express (CME or simply “Express”) system.

CME is usually deployed for single or remote sites with under 100 phones, but it can expand to 700 phones (though I wouldn’t recommended it). When using Express, most of the configuration is done by command line or the rudimentary GUI interface. What many people don’t realize is that CUCME can be configured  with Presence features, without the use of a MCS server.

With just a few simple commands and the use of SIP, CUCME can support presence. The configuration is simple but will require the configuration of sip phones, h.323 and sccp is not supported is this configuration. So how do you do it?

  1. Enable presence for internal lines
  2. Enable a directory number to be watched
  3. Enable a SCCP or SIP phone to monitor BLF status for speed dials and call llists
  4. Configure presence to watch external lines
  5. Verify and troubleshoot presence configurations

Step 1: Enable presence for internal lines

routerA(config)# sip-ua

routerA(config-sip-ua)# presence enable

routerA(config)# presence

routerA(config-presence)#presence call-list

routerA(config-presence)#max-subscription number

 

Step 2: Enable a directory number to be watched

routerA(config-ephone-dn # or router(config-register-dn ) allow watch

 

Step 3: Enable a phone to monitor BLF status

routerA(config-ephone)# or router(config-register-pool)#  blf-speed-dial tag number label string

 

 

Step 4: Configure presence to watch external lines

routerA(config-presence)#

 

Step 5: Verify and troubleshoot

Cisco Presence is a real-time indicator of user availability while integrated with a Cisco Unified Communication cluster. It integrates with calendaring, location and workflow systems,  allowing users to automatically share their status with other users. Presence reside on a single or multiple servers depending on the number of users you want to provide presence capabilities.   However, Presence features aren’t just deployments that include a CUCM  and Presence, it call also be incorporated in a Cisco Unified  Communication Manager Express System.

CUCME are usually deployed for single or remote sites with under 100 phones , but it can expand to 700 phones, I wouldn’t recommended it .  When using express, most of the configuration is done by command line or the rudimentarty GUI interface.  What many people don’t realize is the a CUCME can be configured  with Presence features, without the use of a MCS server.  With just a few simple commands and the use of SIP , CUCME can support presence.

So  how do you configure presence for CUCME.

Presence Service Configuration

1.Enable presence for internal lines

2.Enable a directory number to be watched.

3.Enable a SCCP or SIP phone to monitor BLF status for speed dials and call llists

4.Configure presence to watch external lines

5.Verify and troubleshoot presence configurations

Step 1    Enable presence for internal lines

routerA(config)# sip-ua

routerA(config-sip-ua)# presence enable

routerA(config)# presence

routerA(config-presence)#presence call-list

routerA(config-presence)#max-subscription number

Step 2  Enable a directory number to be watched

routerA(config-ephone-dn # or router(config-register-dn ) allow watch

Step 3  Enable a phone to monitor BLF status

routerA(config-ephone)# or router(config-register-pool)#  blf-speed-dial tag number label string

Step 4

routerA(config-presence)#

Presence is usually integrated with Cisco’s Commnication Manager  which provides the call control for a Cisco Unified Communication cluster. Typically, Communication Managers are used in larger deployments when there are 300 or more phones.  With Communication manager Expresss presence can be deployed  in a CUCME system like that of its big brother. The configuration is quite simple but will require the configuration of sip phones, h.323 and sccp is not supported is this configuration.
