Outbound Dialers with Service Cloud Voice for Partner Telephony
Preview (Push) Dialer
A preview dialer works similarly to callbacks. The Connector publishes PREVIEW_CALL_STARTED and the agent gets a request agent work item, which can be accepted or declined. After the call is accepted, the connector publishes a CALL_STARTED event. After the customer connects, the connector can publish CALL_CONNECTED. Salesforce creates the inbound voice call in preview mode.
Progressive Dialer
A progressive dialer works similarly to inbound calls. The vendor telephony system dials the customer without notifying the agent. After the customer picks up the call, the vendor follows the inbound call flow (that is, create a Voice Call, send CALL_STARTED, accept or decline).
