IMG 1010 - Originating Line Information ISDN-SIP
Overview:
The Originating Line Information parameter conveys information about the originator of a call. Initially, the IMG supported inter-working the ISUP-OLI parameter when passing information from SS7 to SIP and SIP to SS7. F-5117 'Support ISUP-OLI for ISDN-SIP call' adds support when inter-working the ISUP-OLI parameter from ISDN-SIP and SIP-ISDN. When inter-working the ISUP-OLI parameter from ISDN to SIP, the ISUP-OLI parameter is added to the From: Header in the SIP INVITE message. When inter-working the ISUP-OLI parameter from SIP to ISDN, the ISUP-OLI parameter is added to the SETUP message on the ISDN leg. Below explains what is supported and how it is configured.
