Starting with Version H V 1.0, directed call pickup, regardless of
any call pickup group affiliation, is possible. This feature allows waiting,
switched off, or manually held calls at any user to be queried network-wide.
In directed call pickup, you select the feature code (PUDIR) or select
the menu option at the terminal and specify the number of the dialed
apparatus. This feature applies both locally and network-wide, but is
not connected to the classically configured call pickup groups. This
mean users can use this function even if they are not in a call pickup
group. With the COS authorization (BDCP), a user can protect himself
or herself from a directed call pickup. With the COT parameter NQNP,
you can block a line for a network wide call pickup (for example, for
systems that do not support the feature).
