Features & Enhancements
Control Default IVR Visibility in Call Transfers (/app) (EN-246):

- New Control: addDefaultIvrFeatureContextsForCampaign flag in server_preference_store.
- Default Behavior:
- Shows for inbound campaigns unless disabled.
- Setup Options:
- CC-level: Affects all campaigns in the Contact Center.
- Campaign-level: Targets specific campaigns only (overrides CC-level).
- Impact: Only changes the IVR dropdown list. Transfers and routing unchanged.

Mandatory Warnings for Critical Admin Actions (EN-143):
- New Protection: All high-impact admin actions now trigger irreversible-impact warnings with required confirmation (ECC password).
- Platform-wide Framework: Reusable alerts + full audit logging for every critical action.
- Covered Actions:
- Process Delete
- Process Table Definition Modify
Campaign Delete
User Delete
Email Media Profile Delete
Table Definition Delete
- Routing Rule Delete/Modify/Inactive
- Routing Policy Delete
- No accidental deletions—safer admin experience.
Auto Noise Suppression in GWT WebRTC SDK (EN-290):
- Feature: Lightweight noise cancellation automatically reduces background noise in calls.
- How it Works:
- Enabled by default via backend flag: disableWebrtcNoiseSuppression (set to false in server_preference_store at Contact Center level).
- No UI changes or WebRTC issues.
- Safe fallback if unsupported.
- Pilot tests confirm cleaner audio.
- Toggle off via flag if needed.
Security Fixes
Fixed CSP Misconfiguration (object-src Vulnerability) (GA-15260):
- Security Fix (Infosec): CSP header updated post-patch upgrade.
- Resolution:
- Changed object-src 'self' to object-src 'none'—no active vulnerabilities remain.
- Scan "issues" are now just informational recommendations (optional hardening).
- Validated compliant via standard CSP tools.
- Secure configuration confirmed and resolved.
- Documentation Link (Internal)
CIS Hardening for 4x base OS (GA-133):Â
- A CIS Benchmark compliance assessment was conducted on a Rocky Linux 8 system deployed using a minimal OS image. The objective of this assessment was to establish a baseline compliance status prior to full CIS hardening and remediation.
- Benchmark comparison was performed against previously validated environments:
- CIMB Setup: rocky_cis_report_CIMB.html
- Porter Setup: porter_cis_report.html
- The identified non-compliant controls are documented and tracked in the CIS-Benchmark sheet – Rocky8, which serves as the official remediation tracking artifact. All findings are under review, and remediation actions are planned to align the system with CIS benchmark requirements.

UI/UX Bugs
Fixed Call ID Search Across All Pages (SL-17831):
- Issue: When supervisors searched call records using a Call ID, the results were shown correctly on the first page. However, when moving to the next page, some matching records were missing.
- Fix: The search value is now correctly passed for all pages. Supervisors can now see all matching call records across pages when searching by Call ID.
- Supervisors see complete results—no more missing calls on later pages.

Fixed Auto Preview Dial After Agent Break (DCA20260105728410) (SL-17915):
- Issue: An issue was observed in Auto Preview Dial where, after completing a call and moving the agent to Break, the next call attempt could fail when the agent became Available again and clicked the Call button. This happened due to a temporary mismatch in the UI, which caused the system to attempt dialing an incorrect number for the previewed customer.
- Fix: The UI handling has been improved to ensure the correct previewed customer details are always used when initiating a call.
- This ensures a smooth and reliable calling experience when agents move between Available and Break states during Auto Preview Dial.
Fixed Sleep Mode State Glitch (DCA20251112704300) (SL-17751) :
- Issue: In certain scenarios, when a user’s system enters sleep mode (commonly on Windows), the network may be temporarily suspended by the operating system. This can cause the real-time push connection to break while the application is still open.
- Fix: To maintain session stability and prevent inconsistent application states, the system includes enhanced handling for such scenarios.
- Wake from sleep → back to normal operations instantly.
