This section describes which SIP headers to use when determining the Calling Party information.
To View and Edit Calling Party
On the SBC main screen, go to All > Address Context > Zone > SIP Trunk Group > Signaling > Calling Party.
The Calling Party window is displayed. Use the drop-down box to select the desired Address Context, Zone, and SIP Trunk Group. The Edit Calling Party window is displayed. Figure 1: Sip Trunk Group - Signaling - Calling Party The following fields are displayed: Table 1: Sip Trunk Group - Signaling - Calling Party parameters Parameter Description Pai For Calling Party If enabled, the PAI header (if present) will be accepted to form the Calling-Party-ID. Ppi For Calling Party If enabled, the PPI header (if present) will be accepted to form the Calling-Party-ID. Rpi For Calling Party If enabled, the RPI header (if present) will be accepted to form the Calling-Party-ID. Enabled (default) NOTE: Both Ppi For Calling Party and Rpi For Calling Party 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. From Hdr For Calling Party If enabled, the FROM header will be used to form the Calling-Party-ID provided no allowed PAI/PPI/RPI header is present. When enabled, the SBC maps the ISUP Calling Party Number to SIP From and PAI Headers. For more information, refer to SIP-I Support. When enabled, the SBC maps the From header to ISUP GAP parameters. For more information, refer to SIP-I Support. Cpc Param From Header Specifies the SIP Mapping CPC parameter from incoming call to outgoing Trunk Group call. Trusted Source For Isup Used to indicate if the message came from a trusted source and the FROM header can be used to map into ISUP parameters.
