ISDN Features and Supplementary Services
Calling Number Identification Service (CLIP/CLIR)
The Calling Number Identification Presentation (CLIP) and Calling Number Identification Restriction
(CLIR) services provide for:
•
Delivering a redirecting number to and from a PRI interface.
•
Populating a PRI calling number with the original provisionable Signaling System 7 (SS7) calling
party number (CPN), or the charge number (CN), if available.
•
Transferring a connected number received in a connect message end-to-end on a PRI-to-PRI call.
Redirecting Number Support
Redirecting Number IE support is available for NI2/4ESS and 5ESS switch types, and allows passing a
redirecting number IE from one call leg to another. DMS Original Called Party Number support is also
available. This allows the Cisco BTS 10200 Softswitch to receive an original called party number
(OCPN) from an incoming PRI (configured as DMS-100), and to send an OCPN to a PRI (configured as
DMS-100) interface.

Sent if:
facil-ie-supp=y;

DISPLAY IE

Facility IE carrying Cname is supported in the
SETUP message in both the user-to-networks
and network-to-user directions as an optional
IE. The Facility IE is ASN.1 encoded.
The raw display value overrides the standard
use of Facility IE. When cname-encode-
method=raw-disp, calling, or connected, name
is carried in a Display IE as a null terminated
ASCII string.

Calling, or called, name functionality is not
supported by the standard in either a Display
IE, or a Facility IE.
However, if the raw display cname-encode-
method token is configured, the calling or
connected name is carried in a Display IE as a
null terminated ASCII string.
