After Hours - Need Calls to Ring in my Office as Well

US Account: Our business hours are set as 9 - 5. However, I don't always leave the office right at 5. In addition to our calls being forwarded to our on-call number after 5 each day, is it possible for the after-hours calls to also ring simultaneously to all of our office extensions, so if someone is still in the office, they can pick up the after hours call as well?
