End Call | Smallest AI Docs

End Call tells your agent when to hang up. Without proper end conditions, calls may drag on awkwardly or never conclude. Define clear triggers so conversations wrap up naturally.

Location: Config Panel (right sidebar) → End Call toggle

Setup

Toggle End Call ON
Click the ⚙️ icon to open settings
Click + Add End Call to create a function

Configuration

Each end call function has two fields:

Field	Purpose	Example
Name	Identifier (used internally)	`end_call_resolved`
Description	Tells the AI when to trigger	”End the call when the customer confirms their issue is resolved”

The Description is critical — it’s what the AI uses to decide when to end the call. Be specific.

Common End Call Functions

Issue Resolved

Goodbye

Transfer Complete

No Response

Field	Value
Name	`end_resolved`
Description	”End the call when the customer confirms their issue is completely resolved and they have no additional questions.”

Tips

Be explicit about triggers

Vague	Specific
”When done"	"When customer confirms satisfaction"
"If goodbye"	"When customer says goodbye, thanks, or indicates they’re finished”

Cover edge cases

Don’t just handle the happy path:

Customer explicitly asks to end
Customer becomes unresponsive after 3 prompts
Customer requests callback instead

Stay consistent with your prompt

If your main prompt says “end when resolved,” your end call description should match that language.

Create multiple functions

Think through every way a call might conclude:

Function	Scenario
`end_resolved`	Issue fixed, customer happy
`end_goodbye`	Customer says goodbye
`end_transfer`	After transferring
`end_no_response`	Caller stopped responding
`end_out_of_scope`	Can’t help, directed elsewhere

Transfer Call

Hand off to human agents
