Nov 1, 2025November 2025 monthly summary for nethesis/ns8-nethvoice. Focused on reliability and maintainability around TLS certificate deployment and routing. Delivered two major features with extensive refactors to agent.set_route, enabling consistent route configuration and improved operational visibility. Key outcomes: (1) Let’s Encrypt Certificate Deployment Reliability and DNS Readiness: DNS pre-checks before certificate requests, streamlined routing for certificate flow, consolidating route management via agent.set_route, reducing manual steps and exposure to misconfigurations. (2) Reports Routing Cleanup and Modernization: migrated reports API and UI routing to agent.set_route for cleaner, boilerplate-free configuration. Major bugs fixed: replaced environment variable checks with real-time certificate status via agent.get_route and reporting; removed unused lets_encrypt route key and legacy handling across destroy/restore/update/service events to prevent Traefik restart disruptions. Impact: improved certificate reliability and UI accuracy, reduced maintenance burden, fewer outages due to misrouted TLS flows, easier future changes. Skills: DNS/TLS/LE certificate flows, Traefik integration, NS8 core agent.set_route, refactoring patterns to reduce boilerplate, API/UI routing modernization.

Oct 1, 2025October 2025 delivered automated data maintenance and reliability enhancements for the ns8-nethvoice project. Implemented a systemd-based CDR cleanup workflow to purge Call Detail Records older than 24 hours, with safeguards to verify MariaDB availability and staggered executions to minimize load spikes. Fixed a critical reliability issue in the MySQL CLI invocation by properly quoting all arguments, ensuring script-based DB interactions do not fail when arguments contain spaces or special characters. These changes improve data hygiene, system stability, and automation coverage, delivering tangible business value through more predictable maintenance windows and fewer DB-interaction errors.

Jan 1, 2025January 2025 (2025-01) focused on stabilizing deployment reliability for the ns8-nethvoice repository by addressing environment variable handling under systemd. The primary effort was a bug fix in the freepbx.service: environment variables with special characters were not loaded correctly due to systemd parsing quirks. The solution updated ExecStart to prepend runagent before invoking podman, bypassing systemd's variable parsing quirks and ensuring proper loading of environment variables. This fix improves startup stability and reduces deployment-time failures related to environment configuration. The change is captured in commit e852f93583bf98d8cb8036df247fe20e9a2ecda1 with message 'fix(systemd): fix env vars with special chars'.
