The CUCM Presence configuration procedure includes the following three steps:
Step 1 Enable Presence-enabled speed dials:
a. Customize phone button templates to include Presence-enabled speed dial
buttons.
b. Apply phone button templates to phones.
c. Configure Presence-enabled speed dial buttons.
d. Apply subscribe calling search space to phones.
Step 2 Enable Presence-enabled call lists. Enable the BLF for Call Lists
enterprise parameter
Step 3 Allow Presence subscriptions through SIP trunks. Enable CUCM
Presence on SIP trunks.
Presence-enabled speed dials and call lists are independent of each other. Presence
subscriptions can work between vendors or CUCM clusters through SIP trunks.
The first step for implementing Presence-enabled speed dials is to configure a phone button
template that includes Presence-enabled speed dials. To configure a phone button template,
go to Device > Device Settings > Phone Button Template and either add a new template
or copy one of the default phone button templates and save it with a new name. Configure
the phone button template with the desired number of Presence-enabled speed dials, as
illustrated in Figure 17-3.

NOTE In CUCM Administration, Presence-enabled speed dials are called speed dial
BLF.

Assign the previously configured phone button template to the IP phone as shown in Figure
17-4. Navigate to the Phone Configuration page from CUCM Administration (Device >
Phone > Find) and select the appropriate template from the Phone Button Template dropdown
list. Save the configuration and reset the device.

After the new phone button template has been applied, the Presence-enabled speed dials
display in the Association Information area of the Phone Configuration page (left side). The
phone can now use buttons for Presence-enabled speed dials. To configure the Presenceenabled
speed dials, click the Add a New BLF-SD link shown in Figure 17-5.

The Busy Lamp Field Speed Dial Configuration window will pop up after you click the
BLF-SD link. Configure the target (Presence entity to be watched) of the Presence-enabled
speed dial button, and a label will display on the phone screen next to the corresponding
button. Figure 17-6 shows this configuration.

If call lists should also provide Presence information, the appropriate enterprise parameter
has to be enabled, as shown in Figure 17-7. After you change this enterprise parameter, all
phones that support Presence have to be reset for the change to become effective.

If Presence subscriptions will be used over a SIP trunk, Presence must be enabled on the
SIP trunk. Presence is enabled through the SIP trunk security profile, not directly at the SIP
trunk. Configure a SIP trunk security profile from System > Security Profile > SIP Trunk
Security Profile configuration pages. The Accept Presence Subscription and Accept
Unsolicited Notification check boxes should be checked to enable SIP Presence
information, as shown in Figure 17-8.
Enable presence-enabled call lists.
