Brief Description:

The Originating Line Information parameter conveys information about the originator of a call.

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. See Related links below for more information.
