Agent add-ons for transfers, texts and alerts
Extend your AI phone agent with call transfer, texting, emergency alerts, calendar booking and lead capture, and see which plan each add-on needs.
Add-ons give your agent extra abilities during or after a call, such as passing a caller to a person, sending a text, alerting you to an emergency or booking onto your calendar. Each add-on is a card with its own toggle, and each agent has its own add-ons.
Where to find add-ons
Section titled “Where to find add-ons”- Open AI Phone Agents and select the settings icon on your agent.
- On the Instructions tab, scroll to Add-on Capabilities. Select its heading to collapse or expand it.

For Calendly you enter a Calendly Personal Access Token, an Event Type URI and a Timezone, plus an optional Internal confirmation email (optional) used when a caller will not share an email. For Cal.com you enter a Cal.com API Key, an Event Type ID and a Timezone.
Lead Capture, Send to your CRM
