Configures Presence Eventlist URI to monitor the extensions on Multi-

Eventlist URI on the service side first (i.e., presence@myserver.com) with a

field, fill in the URI without the domain (i.e., presence). To monitor the
extensions in the list, under Web GUISettingsProgrammable Keys
page, please select "Presence Watcher" in the key mode, choose account,
enter the value of each extension in the list.
Configures the Eventlist BLF URI on the phone to monitor the extensions in
the list with Multi-Purpose Key. If the server supports this feature, users need
to configure an Eventlist BLF URI on the service side first (i.e.,
BLF1006@myserver.com) with a list of extensions included. On the phone,
in this "Eventlist BLF URI" field, fill in the URI without the domain (i.e.,
BLF1006). To monitor
