DialNexa agent settings control what a published agent version can do during and after a call. They cover tools, speech behavior, call timing, fallback variables, post-call extraction, and webhook event enablement.
The prompt tells the agent what to say. Settings decide what happens when the caller goes silent, asks for a booking, triggers a transfer, or leaves data behind.

​
Settings Areas

Each panel answers a different operational question.

Functions

What actions can the agent perform during the call?

Speech Settings

How should the agent listen, respond, denoise, cache audio, and handle language-specific speech behavior?

Call Settings

What happens with voicemail, silence, maximum duration, ambient noise, and call timing?

Fallback Settings

What default values should dynamic variables use if launch data does not provide them?

Post-Call Analysis

What structured fields should DialNexa extract after the call?

Webhook

Should this agent emit real-time webhook events?

​
Settings And Version State

Many settings belong to the agent version, so version state matters.

Only enable events when a receiver endpoint and secret are ready.
