Use the callingParty parameter for the SBC Core to specify which SIP headers are used when determining the Calling Party information.

Note

Both ppiForCallingParty and rpiForCallingParty options are not applicable in Q.1912.5 SIP-I to SIP-I scenarios. Based on the Q.1912.5 recommendation, the mapping to calling party number only occurs if a PAI header containing valid address digits (0-9) are received.
