### Answer Yes, you can use dynamic variables in the transfer_call tool's phone number field. [(1) ]() According to the documentation, dynamic variables work in call handling features including "Transfer call phone numbers". This means you can use the

{{variable_name}}

syntax in the transfer destination phone number field, even when doing static routing. For example, you could set up a dynamic variable like

{{transfer_number}}

and pass different phone numbers per call, allowing the agent to transfer to different destinations based on the context of each specific call.
