- HTTP status: 409
- Retry: No: fix the request first
- details: `reason`.

## What happened

The send cannot become a conversation message.

## Why

The message cannot be tied to a conversation: the sender has no Line, the Binding is not attached to a Line, the conversation has no address to send to, or the address is not one the channel uses.

## How to fix it

Attach the number or Binding to a Line in the dashboard, or send to an address the channel uses.
