Dynamic Caller ID

With Tresta’s dynamic caller ID, you can use your business number and personal number on the same phone, while keeping your personal and professional lives separate.

Incoming calls can be configured to show either your business number as the caller ID or the actual caller’s caller ID.

Outgoing calls will show your business number as your caller ID, so your personal number stays private.

Frequently Asked Questions

How do I get the iOS app?

Tresta’s mobile app is available in the Apple App Store.

Does the Tresta app use my cell phone minutes?

Yes. Tresta uses your cell phone carrier to forward calls through the app, so any calls you place or receive through the app will use minutes from your cell phone plan.

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?
