Calling Party Number Options for Outgoing SETUP Message


Calling Party Number Options for Outgoing SETUP Message


This feature allows the service provider to control the calling party number (CPN) data sent in the outbound SETUP message on redirected calls outbound from the Cisco BTS 10200 Softswitch to the PSTN. You can provision this option (via CLI command) using the SEND-RDN-AS-CPN token in the TRUNK-GRP table:

If this token is set to Y (yes), the system overwrites the existing CPN with the redirecting number (RDN) and includes the new value in the outbound SETUP message.

If this token is set to N (no), the system does not change the existing CPN data.
N is the default value.

This feature is applicable to the following scenarios:

Redirection by a subscriber phone

Redirection of a basic or Tandem call

Figure 1 shows an example of the networks and phones involved in redirection by a subscriber phone. Table 1 explains how to provision the SEND-RDN-AS-CPN token for various call-redirection scenarios and results.

On-net to off-net call (either of the following):

RDN=

Off-net to on-net to off-net call:

Inbound off-net call -> B -> fwd -> off-net

Note In this example, the existing RDN
(from the incoming SETUP message)
is 817-555-8888.
The new RDN is the DN of the forwarding phone, Subscriber B—972-555-2222.

CPN=

CPN=

Figure 2 shows an example of the networks and phones involved in redirection of a basic or Tandem call. Table 2 explains how to provision the SEND-RDN-AS-CPN token for call-redirection scenarios and results. Note that the content of the outbound SETUP message depends on whether the RDN is available in the incoming SETUP message.
