Configuring ISUP Parameter Extraction

Configure this parmameter to define a list of ISUP parameters the SBC extracts and interworks during IAM to INVITE interworking for SIP-I to SIP and SIP-I to SIP-I calls. In addition, for SIPI outbound calls, both SIP to SIPI and SIPI to SIPI calls, the SBC interworks parameters from ACM/CPG messages into 18x messages.

To use this feature, set the parameters to extract for the applicable interface using the extract-isup-params parameter in the sip-isup-profile.

To set ISUP format interworking:

In Superuser mode, access the sip-isup-profile using the following navigation.

ORACLE# configure terminal
ORACLE# (configure) session-router
ORACLE# (session-router) sip-isup-profile

Create a new profile, or select the desired sip-isup-profile.
Set the extract-isup-params within the profile referring to the following syntax.
```
ORACLE(sip-isup-profile)#extract-isup-params calling-party-number
```
- calling-party-number
- generic-number
- location-number
- user-to-user
- inband-announcement
Repeat the step above to add additional ISUP values for extraction. (This parameter accepts only one value at a time.)
Apply your sip-isup-profile to the appropriate sip-interface.
Refine you list, if necessary, using the remove-isup-params command followed by the parameter name you want to remove.
```
ORACLE(sip-isup-profile)#remove-isup-params user-to-user
```
Save your work.
