# DialNexa Glossary

> Look up DialNexa glossary terms for agents, versions, phone numbers, batch calls, workflows, integrations, webhooks, variables, transcripts, recordings, and call logs.

The DialNexa glossary defines the product terms users will see while building and monitoring Voice AI calls. Use it when a dashboard word is unfamiliar or when multiple terms sound similar.

<Tip>
  A shared vocabulary is cheaper than a meeting where everyone means a different version of the same word.
