                        Configuring Presence Service   Restrictions for Presence Service Restrictions for Presence Service  Presence features such as Busy Lamp Field (BLF) notification are supported for SIP trunks only;  these features are not supported on H.323 trunks.  Presence requires that SIP phones are configured with a directory number (using dn keyword in  number command); direct line numbers are not supported.
