Due to load balancing and high availability, we do not anticipate any disruption to critical services during this maintenance window. Regional clusters will be upgraded one at a time, with calls automatically routed to the remaining active clusters.



Recommendations

To ensure seamless failover, please confirm your SBC configuration includes:

1. OPTION messages enabled for keepalive checks

2. Paths configured to both primary and secondary 9Line call server clusters
