-# 3CX Ring Group Scheduler
+> **This repository has been archived.** The ring scheduler was merged into [afterhours-shift-manager](https://github.com/Sea-Haven-Industries/afterhours-shift-manager) as a 4th Lambda function in [PR #62](https://github.com/Sea-Haven-Industries/afterhours-shift-manager/pull/62). The CloudFormation stack `ring-scheduler-3cx` has been deleted. All future development happens in the afterhours-shift-manager repo.
 
-AWS Lambda that automatically updates the after-hours and holiday forwarding destinations on a 3CX ring group daily at 8am ET.

-## How it works
+# 3CX Ring Group Scheduler (Archived)
 
-- Two EventBridge rules fire daily (one for EST, one for EDT) to handle DST
+This Lambda updated after-hours and holiday forwarding on a 3CX ring group daily at 8am ET. It has been superseded by the `afterhours-ring-scheduler` function in the [afterhours-shift-manager](https://github.com/Sea-Haven-Industries/afterhours-shift-manager) stack, which uses the 3CX Queue API at extension 801 and reads schedules from DynamoDB instead of a YAML config file.
-- Lambda checks if it's actually 8am Eastern — skips if not
-- Reads the weekly schedule from `config/schedule.yaml`
-- Authenticates to 3CX V20 XAPI via OAuth2
-- Updates the ring group's "office closed" and "holiday" routing
-
-## Schedule config
-
-Edit `config/schedule.yaml` to change the weekly schedule or add exception dates:
-
-```yaml
-ring_group_number: "800"
-
-weekly_schedule:
-  Monday: "114"
-  Tuesday: "115"
-  Wednesday: "114"
-  Thursday: "115"
-  Friday: "116"
-  Saturday: "100"
-  Sunday: "100"
-
-exceptions:
-  "2026-12-25": "100"
-```
-
-## Setup
-
-### 1. Create 3CX API client
-
-In 3CX Admin Console > Integrations > API, create a new client with XAPI access enabled.
-
-### 2. Store credentials in SSM
-
-```bash
-aws ssm put-parameter --name /3cx-scheduler/domain --value "yourcompany.3cx.us" --type SecureString
-aws ssm put-parameter --name /3cx-scheduler/client_id --value "your-client-id" --type SecureString
-aws ssm put-parameter --name /3cx-scheduler/client_secret --value "your-secret" --type SecureString
-```
-
-### 3. Deploy
-
-```bash
-sam build
-sam deploy --stack-name ring-scheduler-3cx --resolve-s3 --capabilities CAPABILITY_IAM --parameter-overrides Timezone=America/New_York
-```
-
-## Manual invocation
-
-```bash
-# Run using today's schedule
-aws lambda invoke --function-name 3cx-ring-group-scheduler \
-  --payload '{"force": true}' \
-  --cli-binary-format raw-in-base64-out output.json
-
-# Override to a specific extension
-aws lambda invoke --function-name 3cx-ring-group-scheduler \
-  --payload '{"force": true, "override_extension": "100"}' \
-  --cli-binary-format raw-in-base64-out output.json
