4. 3. 2 Presentation of the CLIP on the Terminal
Call from the Public Network
If a call originates from the public network, the prefix for Exchange access, business
followed by a hyphen is added to the CLIP number (e.g. 0-333 33 33) so that the called
party can call back simply by dialling the number displayed.
Call from a PISN User in a Virtual Network
If a call originates from a PISN user in a virtual network, the call number to the PISN
user is used to convert the CLIP number into the PISN user number and NPI is set to
PNP (see also examples on page 101
).
Destination is not a system phone
If the destination is not a system phone; the CLIP number is handled in the same way
as with system phones but without adding a hyphen.
Calls with suppressed CLIP (CLIR)
If a caller uses the CLIR function to suppress his CLIP display to the called party, the
system phone displays Number suppressed instead of the CLIP.
Calls without CLIP
Number unknown is displayed on the system phone for calls without CLIP.
4. 3. 3 Replicating the Name Display in the Communication
Server
The communication server will try to assign a name to the CLIP number of an incoming
call from the public network and to display that name on the system phone (CNIP). A
search is therefore carried out in the communication server directories for a match for
the CLIP number. The directories are searched in the following sequence:
• PISN user list
• Abbreviated dialling list
• Local directories of the system phones
A name will be displayed depending on the search result as shown in Fig. 33
.
CNIP and CONP are supported in the private leased-line network under QSIG. They
are both accepted and do not need to be recreated in the communication server.
