Best Practice Detail
13-9-0569
Network Operators, Service Providers, and Public Safety should consider using the Public Switch Telephone Network (PSTN) as a backup to dedicated trunks for the 9-1-1 network during periods of network failure. In cases where the ability to deliver 9-1-1 calls to the Public Safety Answering Point (PSAP) through normal routing is interrupted by a failure (not all trunks busy conditions) consider forwarding the call over the PSTN to a telephone number specified and answered by Public Safety authorities. It is desirable for that specified telephone number to be a type that can provide the original Caller ID/Automatic Number Identification (ANI).
Status: Rollover New
References/Comments: This best practice does not propose that any 9-1-1 call delivery stakeholder bypass acceptable congestion control techniques commonly applied within the industry for 9-1-1 calls.
