- **Optimized Call Transfers:** New configuration options to control "Default IVR" visibility during transfers.
- **Audio Quality Improvements:** Introduction of backend-controlled noise suppression for GWT WebRTC.
- **Security Hardening:** Updates to Content Security Policy (CSP) and CIS Benchmark assessments.

# Features & Enhancements

***Control Default IVR Visibility in Call Transfers (/app) (EN-246):***

- **Change:** Agents no longer see Default IVR option by default during transfers—prevents wrong selections.
- **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.
- Documentation [Link](https://exotel.atlassian.net/wiki/spaces/ARCH/pages/1038712881/Configurable+Default+IVR+in+Transfer+Context) (Internal). **Note: **Not Implemented in Toolbar ([Link](https://exotel.atlassian.net/browse/EN-906))



***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

- 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](https://exotel.atlassian.net/wiki/spaces/~7120207e55c94736a4446db52bb4ef909437ac/pages/edit-v2/1587412993?draftShareId=67588fd1-2552-46ed-bc49-5890a2988d49) (Internal)

***CIS Hardening for 4x base OS (GA-133)*: **

- 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.
