Yes and yes. If you're already using CallRail or CallTrackingMetrics, simply connect your call-tracking account to your Switchbird inbox and we'll "listen" for call/text activity on your tracking numbers. You can text your contacts back through those numbers via Switchbird or "delegate" text activity to a number on our platform for more features/lower cost (recommended). If you don't already track your calls, call- and text-tracking is baked-in to Switchbird: just add Twilio numbers to track calls and texts from different channels
