Frequently Asked Questions

What’s the difference between the web app and the mobile app?

The web app is used primarily as a configuration portal for your phone system (changes to users, departments, call routing, etc), but you can also use it to report on your calls and to access your call recordings and voicemails. The mobile app is used for calling and texting, and to retrieve call recordings and voicemails.

Do I have to use the mobile app to use Tresta?

Yes and no. The mobile app is required to place calls and to send and receive text messages. If you don’t care about these features, though, you can receive your calls via call forwarding and do not need to install the mobile app.

I have other questions. Who can help me?

If you have additional questions, we’d love to talk with you. Our product specialists are available 24/7 – visit our contact page for details on how to reach us by phone, chat, and email.
