Call waiting allows users to see when a second call is coming in while on an active call. Users can answer the new call, placing the standing call on hold, and switch back and forth. Call waiting is signified with a light on the handset. Various phone models can hold up to five (5) calls ‘on hold,’ in addition to the active call.
This feature is helpful when you’re on hold with a vendor, but someone on your team is calling you with a question. You’ll see the call coming in and pick it up, placing your vendor call on hold without losing your place in line. Once you’ve answered the question, simply switch back to the vendor call.
