GSM
| Feature/Component/Service | What it does | 
|---|---|
| describes the information shared by components that implement reorigination for GSM and CDMA networks | |
| receives a CAP trigger, stores reorigination information, and is able to forward the call such that it is routed into the IMS. It enables processing circuit-switched originating calls in the SCC-AS. Reorigination for terminating calls can be bypassed if the subscriber is not registered in the IMS network | |
| triggered from the I-CSCF and retrieves reorigination information; optionally it can retrieve the subscriber’s assigned S-CSCF either from a HSS or from a profile from network configuration, then acts as a B2BUA between the I-CSCF and the subscriber’s assigned S-CSCF | 
CDMA
| Feature/Component/Service | What it does | 
|---|---|
| receives CDMA OriginationRequest and AnalyzedInformation triggers, stores reorigination information, and is able to forward the call such that it is routed into the IMS | |
| triggered from the I-CSCF and retrieves reorigination information. It retrieves the subscriber’s assigned S-CSCF either from an HSS or from a profile from network configuration and then acts as a B2BUA between the I-CSCF and the subscriber’s assigned S-CSCF |
