IMG 1010 - P-Charge Header - SIP to SS7
Overview:
The P-Charge Info Header in the SIP URI indicates the number which will be billed for a particular call. The P-Charge Info header is much like the Charge Number parameter in ISUP. The IMG supports inter-working the Charge Number information (information about the party to be billed for a call) from SS7/ISUP signaling to the URI in a SIP INVITE message. With the introduction of Feature F-1637 in 10.5.1_ER5 the IMG now supports interworking the P-Charge Info Header from both SIP to SS7/ISUP and SIP INVITE message on incoming leg to SIP INVITE message on outgoing leg. Once the P-Charge Header has been inter-worked to the SS7/ISUP leg, it can be used to generate or interact with other entities to create billing records. See below for more information. NOTE: The information in this feature will pertain to interworking of the P-Charge Info Header from SIP to SS7/ISUP and from SIP to SIP. For information on configuring the IMG to interwork the Charge number from SS7 ISUP to SIP URI, see the IMG 1010 - SS7 Parameter Filter topic.
