I already have a front desk answering — why you?

The front desk covers its hours; Signal covers the rest: busy line, lunch break, absences, after 5 PM, weekends. There's no conflict: conditional forwarding only triggers on no-answer — when your front desk picks up, nothing changes and nothing extra gets billed. Honestly, if your front desk answers 100% of calls, you don't have a missed-call problem — but almost no team holds that score over time (absences, spikes, holidays). One month with the monthly report will tell you how many calls actually slip past them.
