One or more devices in a provider network receive a notification that a border controller (SBC) device has failed and, in response to the notification, modify a backup SBC configuration file for the failed SBC device to create a modified backup configuration file, where the modified backup configuration file replaces carrier-side Internet Protocol (IP) addresses of the failed SBC device with carrier-side addresses of a failover SBC device. The devices send the modified backup configuration file to the failover SBC device to configure the failover SBC device and send a backup router configuration file for a local router associated with the failed SBC device to a local router associated with the failover SBC device, where the backup router configuration file is to configure the local router associated with the failover SBC. The devices also provide, to a domain name system (DNS) server, carrier-side IP addresses for the failover SBC device to replace IP addresses associated with fully-qualified domain names (FQDNs) of the failed SBC device. |

1. A method comprising:
determining, by one or more devices, a failure of a first session border controller (SBC); identifying, by the one or more devices, a second SBC that is designated as a failover SBC for the first SBC and one or more other SBCs; modifying, by the one or more devices and after determining the failure of the first SBC, backup configuration information for the first SBC to create modified backup configuration information,
the modifying including replacing carrier-side Internet Protocol (IP) addresses of the first SBC, within the backup configuration information, with carrier-side addresses of the second SBC; sending, by the one or more devices, the modified backup configuration information to the second SBC,
the modified backup configuration information being to configure the second SBC; sending, by the one or more devices, a backup configuration file, for a first local device associated with the first SBC, to a second local device associated with the second SBC,
the backup configuration file being to configure the second local device associated with the second SBC; and providing, by the one or more devices and to a domain name system (DNS) server, the carrier-side addresses of the second SBC to replace IP addresses associated with fully-qualified domain names (FQDNs) of the first SBC. |
