Multicast and deltacast

Contact Center AI Platform (CCAI Platform) offers multiple features that let you automate call and chat routing between agents and end-users. Routing can decrease end-user wait times and increase agent efficiency.

  • Multicast is the default routing configuration for all sessions, which are communications between an agent and an end-user. Multicast routes sessions to agents assigned to a specified queue. Each has an equal opportunity to answer, and the quickest to respond will get the call or chat.

  • Deltacast is an intelligent routing system unique to CCAI Platform that uses logic to disperse calls to individual agents, rather than giving agents the same opportunity to answer.

Deltacast for calls

If enabled, deltacast extends to the following:

  • Transfers
  • Scheduled calls
  • Calls routed using Direct Access Points (DAPs)
  • Queues with cascade groups enabled
  • Queues with percent allocation groups

This section outlines deltacast routing logic and describes how to enable this feature.

Missed call status

The Missed Call agent status is used for sessions with deltacast enabled. Missed calls are deltacast calls that are routed to an agent and not answered within the Deltacast Timeout time threshold. Missed multicast calls don't put an agent in Missed Call status.

If an agent is placed in Missed Call status, they won't be able to receive new calls until either they or an Admin manually change their status back to Available. Admins can see a count of agents in Missed Call status in the Call Dashboard, Agent page, and in reporting. Agent status and activity information is also available using the API. To be placed in Missed Call status, the agent must have been in Available status. If they are in any other status, Missed Call will still show in reporting but not in the agent adapter.

Missed Call status is independent of the Missed Chat threshold. Calls are not projected to agents in Missed Call status; they are only routed to agents in Available or In-chat status.

Deltacast routing logic for calls

  1. An incoming call is routed to the agent in status Available with the longest duration since they last ended a call.

  2. If the agent does not answer within the time set in the deltacast timeout setting:

    • If there are remaining deltacast attempt counts for the call, the call is routed to an available agent with the next longest duration.

    • If the deltacast attempt count has run out, the call is routed using multicast to the rest of the agents assigned to that queue menu option.

If cascade groups are also being used

  1. If a deltacast call is routed to an agent and the agent does not answer within the time set in the deltacast timeout setting:

    1. When deltacast attempt counts remain for the call, it's routed to an available agent with the next longest duration.

    2. When the deltacast attempt count runs out, the call is multicast to all agents assigned to Cascade Group 1.

  2. If the multicast call to Cascade Group 1 remains unanswered in the set amount of seconds, the call is multicast to all of the agents assigned to Cascade Group 1 and Cascade Group 2.

  3. If the multicast call being offered to Groups 1 & 2 is still unanswered in the set amount of seconds, the call is offered using multicast to all agents assigned to Cascade Group 1, Group 2, and Group 3.

  4. Multicast continues to offer the call to successive cascade groups until an agent accepts the call.

If auto answer is also being used

An incoming call is routed, using deltacast, to the agent in Available status with the longest duration since they last ended a call. Auto answer immediately connects the call to the agent. The agent is notified with a tone and their call adapter begins the 3-2-1 countdown.

The following diagram shows the deltacast routing flow:

Turn on deltacast for calls globally

This section shows you how to switch from the default multicast routing to deltacast routing. Global deltacast settings are inherited by all eligible queues, unless you change them at the queue level. You are not required to turn on deltacast globally to turn it on for individual queues. For more information, see Turn on deltacast for calls at the queue level.

To turn on deltacast for calls globally, follow these steps:

  1. In the CCAI Platform portal, click Settings > Operation Management. If you don't see the Settings menu, click Menu. The Operation Management page displays.

  2. Go to the Routing pane.

  3. Under Call Routing, select Deltacast. The following configuration settings appear:

    • Deltacast Attempt Count: the number of times deltacast should offer an incoming call to a single, eligible agent before switching to multicast.
    • Deltacast Timeout for calls: the amount of time, in seconds, that an has to pick up a call before it is offered to the next agent or queue. You can configure different time thresholds for agents working at a computer and agents using twinning to answer calls on a mobile phone. Agents answering on a mobile phone might need more time to answer than agents working at a computer.
    • Missed Call Threshold: the number of deltacast calls an agent can miss (not pick up in the set timeout threshold) before being automatically set to Missed Call status.
    • Unresponsive Threshold: if Contact Center AI Platform (CCAI Platform) cannot reach the agent adapter to send a chat to the agent, this threshold determines when to place the agent in Unresponsive status.
    • Cascade Timer selection: select this checkbox to skip the cascade group timer if no agents are available in the cascade group.
  4. Configure your deltacast settings, and then click Save routing.

Turn on deltacast for calls at the queue level

Deltacast settings for queues are automatically inherited from the global settings unless you change them for individual queues. You don't need to turn on deltacast globally to turn it on for specific queues.

To turn on deltacast for calls at the queue level, follow these steps:

  1. In the CCAI Platform portal, click Settings > Queue. If you don't see the Settings menu, click Menu. The Queue Menu Settings page appears.

  2. Depending on the type of queue that you want to edit, click Edit / View in either the IVR (Interactive Voice Response), Mobile, or Web pane.

  3. Click the queue that you want to edit.

  4. In the Settings pane, go to the Routing section. Under Routing, each routing capability is marked with either a Global or a Queue label. These labels indicate whether this capability is configured globally or at the queue level.

  5. Click Configure.

  6. In the Routing pane, go to the Call Routing section, and then click Deltacast. The following configuration settings appear:

    • Deltacast Attempt Count: the number of times deltacast should offer an incoming call to a single, eligible agent before switching to multicast.
    • Deltacast Timeout for calls: the amount of time, in seconds, that an has to pick up a call before it is offered to the next agent or queue. You can configure different time thresholds for agents working at a computer and agents using twinning to answer calls on a mobile phone. Agents answering on a mobile phone might need more time to answer than agents working at a computer.
    • Missed Call Threshold: the number of deltacast calls an agent can miss (not pick up in the set timeout threshold) before being automatically set to Missed Call status.
    • Unresponsive Threshold: if Contact Center AI Platform (CCAI Platform) cannot reach the agent adapter to send a chat to the agent, this threshold determines when to place the agent in Unresponsive status.
    • Cascade Timer selection: select this checkbox to skip the cascade group timer if no agents are available in the cascade group.
  7. Configure your deltacast settings, and then click Save.

Optional: Skip cascade group timer

The skip cascade group timer capabilities let you bypass the cascade timer settings and route a call or chat to the next available agent, regardless of your cascade group. With this feature enabled, the call is routed to agents immediately if they are available in the next cascade group.

When disabled, the platform will adhere to the cascade timer settings and wait for the specified time before proceeding to the next group.

  1. In the CCAI Platform portal, go to Settings > Operation Management > Routing.

  2. Under Cascade Timer selection, select the Skip Cascade Group Timer checkbox. By default, this checkbox is unchecked.

  3. Click Save Routing.

Monitoring and reporting for calls

Admins and managers can see agents in Missed Call status in the Logged in agent section of the call dashboard. Agents in Missed Call status are also visible on the Settings > Agents > Agent page. You can click the Filter Settings menu on this page to filter on agent status.

Deltacast for chat

If enabled, deltacast extends to every channel and every queue that uses chat. It applies to all chat types and the following chat flows:

  • Transfers
  • Chats routed through Direct Access Points (DAPs)
  • Queues with cascade groups enabled
  • Queues with percent allocation groups enabled

Eligible agents

To receive a deltacast call, an agent must fulfill one of following requirements:

  • Status is set to Available.

  • Status is In-chat and the agent has not reached the chat concurrency threshold.

    • Chat concurrency is configured globally in Settings > Chat and individually in Settings > Users & Teams > Edit a user (pencil icon).
    • If the agent is assigned to both chat and call sessions, a call counts as one chat toward the chat threshold.

Missed chat status

The agent status Missed Chat is used for sessions with Deltacast enabled. Missed chats are defined as Deltacast chats routed to an agent and not answered within the Deltacast Timeout time threshold. Missed Multicast chats don't count toward Missed Chat.

If an agent is placed in Missed Chat status, they won't be able to receive new chats until either they or an Admin manually change their status back to Available. Admins can see a count of agents in Missed Chat status in the Chat Dashboard, Agent page, and in reporting. Agent status and activity information is also available using the API. To be placed in Missed Chat status, the agent must have been in Available status. If they are in any other status, Missed Chat still shows in reporting but not in the agent adapter.

Missed Chat status is independent of the Missed Call threshold. Chats are not projected to agents in Missed Chat status; they are only routed to agents in Available or In-chat status.

Deltacast routing logic for chat

Basic routing:

  1. When a chat enters the queue, the chat is offered to a single, eligible agent (status Available or In-Chat), according to these rules:

    • If multiple agents are in Available status, the chat is routed to the agent with the longest period of time since they were last in In-Chat status.

    • If all assigned agents are In-call or In-chat, the agent who has the fewest number of concurrent chats will get the next chat.

    • If an agent is on a call, the call counts as [X] concurrent chats as configured in Settings > Operation Management.

    • If multiple agents have the same number of concurrent chats, the agent with the longest period of time since receiving a chat will get the next chat.

  2. If the agent who is offered a chat does not pick up the chat within the time set in the deltacast timeout setting, the chat is offered using Multicast. Multicast sends the chat to every agent in the queue, including the agent who didn't answer the chat in time.

Routing with cascade groups:

  1. The chat is offered to an eligible agent in Cascade Group A for the duration of the Deltacast Timeout for Chats timer. If it isn't answered:

    1. If there are remaining deltacast attempt counts for the chat, the chat is routed to an eligible agent with the next longest duration.

    2. If the deltacast attempt count has run out, then the chat is offered using multicast to all agents in Cascade Group A, both in Available and In-chat statuses, including the original agent routed the chat (if they did not reach the Missed Chat threshold).

  2. If no agents pick up the chat and the cascade group timer expires: The chat is offered using multicast to all agents in Cascade Group A in either Available and In-Chat status, including the original agent routed the chat.

  3. If no agents pick up the chat and the cascade group timer expires: The chat is offered using multicast to all eligible agents in Cascade Group B, and continues to offer the chat using multicast to all eligible agents in Cascade Group A.

  4. If the cascade group timer expires, and Group B is the last group: The chat continues to be routed using multicast until the unanswered chat expiration timer expires, as set in Settings > Chat.

Routing with auto answer enabled:

  1. The incoming chat will be routed using Deltacast to an eligible agent based on the routing logic described previously. Auto answer initiates the chat conversation in the Agent Adapter. The agent will hear an audible tone, and the New Chat tab will flash red.

Turn on deltacast for chat globally

This section shows you how to switch from the default multicast routing to deltacast routing. Global deltacast settings are inherited by all eligible queues, unless you change them at the queue level. You are not required to turn on deltacast globally to turn it on for individual queues. For more information, see Turn on deltacast for chat at the queue level.

To turn on deltacast for chat globally, follow these steps:

  1. Go to Settings > Operation Management, and then go to the Routing pane.

  2. At Chat Routing, select Deltacast. The following configuration settings appear:

    • Deltacast Attempt Count: The number of times deltacast should offer an incoming chat to a single, eligible agent before switching to Multicast.
    • Deltacast Routing Logic: This setting affects the eligible agent calculation. This setting only applies to agents who are assigned to a queue configured for both chat and call channels.
    • Deltacast Timeout for chats: This is the time duration, in seconds, before the chat is offered to the next agent or queue.
      • The suggested value is 10 seconds, which ensures that the chat has enough time to connect in most network connection scenarios.
      • Make sure that percent allocation and cascade group time threshold settings are higher than the deltacast Timeout value. If they are the same or lower, you won't be able to enable deltacast. Group settings are located in the General section of the Operation Management page.
    • Missed Chat Threshold: The number of deltacast chats an agent can miss (not pick up in the set timeout threshold) before being automatically set to Missed Chat status.
    • Unresponsive Threshold: If CCAI Platform cannot reach the Agent Adapter to send a chat to the agent, this threshold determines when to place the agent in Unresponsive status.
    • Cascade Timer selection: Select this checkbox to skip the cascade group timer if no agents are available in the cascade group.
  3. Configure your deltacast settings, and then click Save routing.

Turn on deltacast for chat at the queue level

Deltacast settings for queues are automatically inherited from the global settings unless you change them for individual queues. You don't need to enable deltacast globally to configure it for specific queues.

To turn on deltacast for chat at the queue level, follow these steps:

  1. Go to Settings > Queues > {Web or Mobile channel} > {QUEUE_NAME}.

  2. Go to the Routing section. If you have global deltacast settings enabled, a Global tag appears. All queues automatically inherit global deltacast settings unless you change them at the queue level.

  3. Click Configure, and then click Deltacast to enable it for this queue.

  4. Set your deltacast configuration values, and then click Save. For more information about deltacast configuration settings, see Turn on deltacast for chat globally.

Monitoring and reporting for chat

Admins and managers can see agents in Missed Chat status in the Logged in Agent section of the CCAI Platform Chat Dashboard in the CCAI Platform portal. Agents in Missed Chat status are also visible in the CCAI Platform portal in the Agents > Agent page. You can click the Filter Settings menu at the top of this page to filter on agent status.

View deltacast and multicast chat data

All notifications offered, pickup attempts, and successfully answered chats are logged and can be viewed in reports and reporting APIs. The following reports are available:
