The information below explains the interworking of the Generic Name parameter on the SS7 side with the Remote Party ID, From, and P-Asserted Identity headers on the SIP side.

...

• There are some instances that the remote SS7 carrier will not want the Generic Name Parameter sent to them in the IAM. In this case the Generic Name can be stripped from the IAM message by configuring the SS7 Parameter Filter to strip the Generic Name from the IAM. See SS7 - Destination - ISUP Group - Parameter Filter link

• The Remote Party ID will be interworked only if the parameter party is set to calling.

• If the parameter privacy is not included in the RPID both the Calling Party Number and Generic Name will be allowed

• The Generic Name will be restricted to 15 characters in the Remote Party ID Display portion

...

• The Privacy Header carries the APRI of the Calling Party Number and the mapping is shown above

• The P-Asserted Identity Header display-name portion is mapped into the Generic Name field

• The P-Asserted Identity Header user name portion (if digits) is mapped to the address digits of the Calling Party Number

• A maximum of 15 characters from the P-Asserted Identity Header will be placed into the Generic Name field.

• If there is both a Remote Party ID header and a P-Asserted Identity Header in the INVITE message the P-Asserted Identity Header Values will take precedence.

• To configure Privacy and P-Asserted Identity Headers refer to the SIP Privacy topic for information on configuring.
