Webhooks: Interaction Context Metadata
Webhook payloads for inbound, outbound, and Dialer call events now support an optional interaction_context object. This field provides additional interaction metadata, such as contact identifiers, brand information, or language settings, based on your contact center configuration. For inbound calls, the data can also include mapped custom SIP header values. The interaction_context object is included only when configured for the contact center.

New features
Dialer campaigns: Follow-up mode
Dialer campaigns now include a new Follow-up mode setting that controls how contacts are prioritized for redial attempts:
- The Timer mode maintains the existing behavior, where each contact is redialed according to its configured delay timer.
- The new Lowest attempt mode prioritizes contacts with the fewest dial attempts while still respecting configured redial delay timers, helping to distribute retry attempts more evenly across the contact pool before contacts with higher attempt counts are retried again.
