Bind Connection to Number
Attach a connection (the AI persona / answering brain from SAPERLY_CREATE_CONNECTION) to a phone number, so inbound calls and SMS to that number — and outbound calls placed from it — are handled by that connection. A number without a bound connection cannot answer calls (and PLACE_CALL fails with 422 NumberHasNoConnection), so this is the wiring step that makes a number answerable. Get a connection id from SAPERLY_LIST_CONNECTIONS or create one with SAPERLY_CREATE_CONNECTION. Returns the updated number object. Free.
