MSAG Maintenance and ESN Assignment
Some solutions will dynamically provide the cell site location, subscriber call back number, and lat/long
during 911 call processing. Wireless carriers are still required to provide "static" pseudo-ANI data
records to the E911 host with MSAG valid addresses. These "static" records will be dynamically updated
during 911 call processing. The cell site location information provided during the dynamic updates are
not validated against the MSAG, but the original "static" record provided in the SOIR process will be
validated against the MSAG.
