- Collected AAFD client logs for both working (2.0.6.21.3003) and failing (2.0.6.26.3008) versions and compared registration flows with Communication Manager.
- Identified in the failing logs that:
- ICV authentication failed with “AuthenticateICV … failed” and “incorrect password.”
- Station password (AvayaAgentStation entry) was not stored in the new 2.0.6.26 profile.
- First‑launch configuration files (directive.txt, config.xml) were not copied into the user profile, resulting in incomplete local configuration.
- Verified on Communication Manager that the H.323 security profile “challenge” setting and ip‑network‑region configuration were correct, confirming the issue was client‑side and specific to AAFD 2.0.6.26.3008.
- As an interim action, advised a clean reinstall of AAFD 2.0.6.26.3008 (uninstall, delete local AAFD profile/configuration, reinstall, and manually re‑enter station extension and password) to eliminate corrupted local profile data.
- Escalated the case to Avaya product engineering with logs, configuration details, and trace outputs; engineering confirmed GCF validation failure on port 3008 and non‑reproducibility in the lab.
- Product engineering prepared and provided an updated AAFD build (later than 2.0.6.26.3008, including a 3009 test build during analysis) that corrected the authentication/configuration handling defect.
- End user installed the updated AAFD release on the affected Windows 11 workstation and configured the station credentials again.
- End user confirmed successful login and stable operation with the updated AAFD release, and the SR was closed as resolved.
Notes: Confirm that all necessary permissions have been obtained and system backups are completed prior to implementing any changes. Service‑affecting actions such as client rollouts or changes to Communication Manager security profiles should be scheduled in accordance with maintenance windows and change‑management policies.
