Number Lookup Triggers
Use cases that are applicable to number lookups and the associated Oracle Communications Core Session Manager procedures include:
- Request from the access side:
- The Oracle Communications Core Session Manager performs originating services.
- If the R-URI is a tel-URI or SIP-URI (with user=phone), it requests e.164 resolution from the ENUM server(s), regardless of its presence in the registration cache.
- Request from core side including request for originating services:
- The Oracle Communications Core Session Manager performs originating services.
- If the R-URI is a tel-URI or SIP-URI (with user=phone), it requests e.164 resolution from the ENUM server(s), regardless of its presence in the registration cache.
- Request from core side, for terminating services only:
- If the R-URI is a tel-URI or SIP-URI (with user=phone) and is not in the Oracle Communications Core Session Manager cache, it performs an LIR.
- If the LIA reply indicates the tel-URI or SIP-URI (with user=phone) is not provisioned, the Oracle Communications Core Session Manager requests e.164 resolution from the ENUM server(s).
