10.5.3_SP8.2 - An Overview of Features
F-5963 Calling Party Information Retrieval via INR/INF message (UPDATED)
Brief Description:
When the Calling Party Information Retrieval feature is enabled, if the IAM received from the SS7 side does not contain a Calling Party Number -or- the Calling Party Category is set to unknown the IMG will send an INR (Information Request) back to the SS7 network requesting the Calling Party Number and/or the Calling Party Category. Once the SS7 side receives the INR, it will send back an INF (Information Message) with the requested parameters. The IMG then receives the parameters and uses this information along with the information in the original IAM to generate an INVITE message to either the H.323 or SIP network which includes the additional parameters.
F-5963 was initially introduced in software version 10.5.3 SP8. This feature was supported between the SS7 and SIP protocols. In software version 10.5.3 SP8.2, the H.323 protocol was added. F-5963 Calling Party Information Retrieval via INR/INF message is supported between SS7 and H.323 protocols as well.
