CG-EWCG-001 Wireless E911 Guide
Issue 3, January 6, 2004 PSAP Inquiries
7.5.4 ESN
Investigate as necessary with the E911 Customer to determine the correct address. Update the address
information for the pseudo-ANI TN record by submitting a corrected SOIR with the valid information.
Once resolved, check action: "Trouble cleared as of (enter the date)" and return the inquiry to the
originator. If it is determined that the pseudo-ANI address is correct, check action: "Trouble Referred
to Other on (Enter date)". These Inquiry Forms should be returned to INTRADO for investigation. If it
is determined that a correction in the pseudo-ANI TN record is necessary, INTRADO will contact the
wireless carrier for a new SOIR to be sent.
7.5.5 Misroutes
A misroute indicates the E911 call routed to the wrong PSAP. Routing is determined by the ESN associated
with the matching address record in the MSAG database. Investigate as necessary with the E911 Customer
to determine the correct address. The E911 Customer should be able to assist with identifying the MSAG
valid address and the associated ESN to route the calls to the desired PSAP. Update the address information
for the pseudo-ANI TN record by submitting a corrected SOIR with the MSAG valid information. Check
action: "Trouble cleared as of (enter the date)" and return the inquiry to the originator. If it is determined
that the pseudo-ANI address is correct, check action: "Trouble Referred to Other on (Enter date)". These
Inquiry Forms should be returned to INTRADO for investigation. If it is determined that a correction in the
pseudo-ANI TN record is necessary, INTRADO will contact the wireless carrier for a new SOIR to be sent.
