Normally, when someone calls your Clearstream texting number, the call won't go through. But if you enable the Voice Add-On, you can send incoming calls to a Clearstream voicemail or forward them to your (or a team member's) personal number!
The Voice Add-On is only $10/month and that covers every number in your Clearstream account (including all your subaccounts!). You can enable it by going to Settings > Voice in your main account. More on that here!
If you have any questions, just reach out to us via the live chat in your account. We're happy to help!
