Cisco PGW 2200 Softswitch Display Name and Connected Number Interworking Feature Module
Feature Description
Feature Description
The Display Name and Connected Number Interworking feature introduces a comprehensive structure
for handling the parameters associated with the following features for calls between ISUP and SIP
endpoints:
•
Calling Line Identification Presentation (CLIP)
•
Connected Line Identification Presentation (COLP)
•
Calling Line Identification Restriction (CLIR)
•
Connected Line Identification Restriction (COLR)
These parameters allow the Cisco PGW 2200 Softswitch to support interworking between ISUP and SIP
networks for basic call features, for call forwarding features, and for call transfer features. Call
forwarding features include Call Forwarding Unconditional (CFU), Call Forwarding No Answer
(CFNA), and Call Forwarding Busy (CFB).
This feature enables the Cisco PGW 2200 Softswitch to handle display name and number identity
interworking between PBX and SIP for basic calls, call forwarding, and call transfer.
CLIP/COLP provides call control and security for residential telephone users. It also provides an
automatic means of identification and improved productivity to enterprise customers. In addition,
display name is part of the calling line identity (CLI). Using CLI information within networks enhances
the existing support for call processing, billing, emergency call handling, customer care, operator
assistance services and advanced services.
With this feature, the Cisco PGW 2200 Softswitch can map display name and connected number
between SIP and ISUP, and between SIP and QSIG. This feature also enables support of prefix
modification for connected number, redirection number, and transferred number.

number, and transferred number.
•
The Cisco PGW 2200 Softswitch enables number modification for the Original Called Number.
•

Provisioning Tasks
Prerequisites
The Cisco PGW 2200 Softswitch must be running software Release 9.8(1). Prerequisites for this release
can be found in Release Notes for the Cisco PGW 2200 Softswitch Release 9.8(1) at:
http://www.cisco.com/en/US/docs/voice_ip_comm/pgw/9/release/note/rn981.html
Restrictions or Limitations
The Display Name and Connected Number Interworking feature has the following limitations:
•
This feature is not applicable to half-call scenario calls, such as Network Consultation Transfer
(NCT) and Route Optimization (RO).
•
If the call is transferred under CUCM, when the Cisco PGW 2200 Softswitch receives UPDATE
message from the CUCM, it does not know the state of transferred call (Alerting or Answered).
ISUP just sends CPG with “call transfer active”.

2—calling party number
3—redirecting number
4—calling party number and redirecting number
5—original called number

The numtype value of 5 is added in the Cisco PGW 2200 Softswitch

Example:
Digit strings stored in the full number translation table are case
insensitive. That is to say, if digit strings that you provisioned contain
alphabetic characters, the TimesTen database saves them as uppercase
characters in the full number translation table.
The MML command shown in the following example enables full number translation
for result types:
mml>numan-add:fullnumbertrans:svcname="freephone",numbtype=”1”,
digstring="1234",translatednum="54321"

Troubleshooting the Feature
This section provides the troubleshooting solutions for this feature.
•
Number modification is failed.
Step
Action
Description
Step 1
Check the PREFIX_CONVERT
result type.
Make sure that you have provisioned the result type
PREFIX_CONVERT for the dial plan. This result type
enables the Cisco PGW 2200 Softswitch to support prefix

section on page 11.
Step 2
Check the prefix convert entries.
Make sure that you have provisioned prefix convert entries
to the TimesTen table. Defined values for matching
calling/called/generic number should base on the original
values received on the originating side.
For details, see the “Provision Prefix Convert Entries”
section on page 5.
•
PAID does not contain an empty display name or the ACgPN received from ISUP in the address
field.
