Update firmware when it fixes a relevant fault, security issue, carrier compatibility problem or provides a required feature. Review release notes and test the update on a spare or non-critical unit with the same configuration before touching a remote site.
Leaving a stable installation unchanged can be safer when the update offers no needed benefit and rollback or site access is difficult. That does not mean ignoring firmware indefinitely; track versions and risks. Back up the configuration, confirm power and connectivity, schedule a maintenance window and have a recovery plan. Use firmware approved for the exact Comset model and hardware revision.
