<@1145576664366055464> how can i make the agent know the outbound number she is calling to mid conversation?

Thanks for tagging me <@411738504779792414>. I'll look through relevant sources and get back to you shortly.

### Answer
 For outbound calls, you can use the `{{user_number}}` system variable to access the number being called [(1) ](<https://docs.retellai.com/build/dynamic-variables>) . This variable represents the user's phone number, which for outbound calls is the `to_number` .

You can reference `{{user_number}}` in your agent's prompts, begin message, tool configurations, or other settings where dynamic variables are supported . For example, you could include it in your prompt like: "You are calling {{user_number}}" .

The `{{user_number}}` variable is automatically available as a default system variable and requires no configuration . It will contain the destination phone number throughout the conversation .
