No, you don’t. If you want to go fully softphone, which would mean using the Collaborate tool, all you’d need would be a headset to plug into your laptop. Or, if you wanted to run that from a mobile or tablet device, you can do provided that your device has got a microphone and a speaker. We do find a lot of customers like the mix and match where they still would like a handset when they’re hot-desking or in a fixed office environment but also utilise the Collaborate tool when they’re working either remotely or from home.
