# Get numbers

When this tool is executed, it sets two pipeline variables

* `externalPhoneNumbers` - an Array of external phone number associated with the conversation.
* `url` - a deeplink url to the current conversation.

Both of these pipeline variables can be referenced downstream.

Example use case:

* AI voice receptionist.
* Runs `get numbers` tool.
* Use the url deeplink in a handoff email (Send Email tool) so team members can link directly to the conversation.
