This solution addresses a common need for most contact centers to manage their downtimes.

It aims to achieve this by intercepting all inbound requests in Twilio Studio Flow by invoking a Twilio Function which refers to a Twilio Sync Document holding the confguration.

The code covers the following key elements of the solution:

1. The Flex Plugin that adds a configuration screen for Administrator users
2. The Serverless function that is used to intercept the requests in the Studio Flow
3. The Serverless functions to disable concurrent writes to the configuration

The Flex Downtime Manager Plugin allows you to configure the downtime/offline hours for your contact center along with the responses to be played/sent back.

The plugin allows you to configure the following:

• Regular Working Hours
• Emergency Shutdown
• Holidays
• Partial Days

This section provides visual examples of how to configure each above item:

• Configure Regular Working Hours

• Configure Emergency Shutdown

• Configure Holidays

• Configure Partial Days

• Configure Contact Center Timezone

1.1 copy ./serverless/.env.sample to ./serverless/.env and populate the appropriate environment variables.

ACCOUNT_SID=
AUTH_TOKEN=
TEAM_SCHEDULE_DOC_NAME= (Note: This will be unique name for the twilio sync doc )
SYNC_SERVICE_SID=
TEAM_SCHEDULE_MUTEX_SYNC_UNIQUE_NAME=(Note: This will be unique name for the twilio sync doc acting as write mutex )
TEAM_SCHEDULE_MUTEX_EXPIRY_MINUTES=10

1.2 cd into ./serverless/ then run

npm install

and then

twilio serverless:deploy

Update the studio flows for all the supported channels to have the above function intercept all the inbound requests.
Based on the response of the function (allowThrough and offlineMessage), there will be 2 possibilities:

1. The contact center is experiencing downtime
   Condition: ["yes"===allowThrough]
   Outcome: Say/Send back offlineMessage to the source
2. The contact center is operational
   Condition: ["no"===allowThrough]
   Outcome: Send request to flex

• Sample Webchat Studio Flow

• Sample IVR Studio Flow

3.1 copy ./env.sample to ./env and populate the appropriate environment variables.

REACT_APP_TEAM_SCHEDULE_SYNC_UNIQUE_NAME=// (Note: This will be unique name for the twilio sync doc and same as TEAM_SCHEDULE_DOC_NAME above)
REACT_APP_DOWNTIME_MANAGER_VIEW_NAME=downtime-manager

3.2 Test the plugin locally

twilio flex:plugins:start

3.3 Deploy the plugin

twilio flex:plugins:deploy --major --changelog "Notes for this version" --description "Manage Downtime for contact center"
