Tresta for iOS

Install the Tresta phone app and turn your iPhone into a business phone.

Turn Your iPhone into
Your Business Phone

With the Tresta phone app, you can turn any iPhone into an extension of your virtual phone system and enjoy business-oriented calling, texting and call management features.

Calling

With Tresta’s unlimited calling, you can make and receive calls from anywhere on your business phone number without worrying about your bill – Tresta has no per minute or per call charges.

Texting

Your Tresta number also includes unlimited texting. Send and receive unlimited text messages, photos and videos on your local or toll-free business number.

Dynamic Caller ID

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

Incoming calls will show they’re ringing in on your business number, so you know which calls are personal and which are business.

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

Contact Syncing

Tresta automatically syncs with your phone’s contacts, and any users, departments and extensions that you configure are added to the directory, too. This way, anyone you want to call or text is just a click away.

Voicemails & Call Recordings

Tresta’s visual voicemail and call recording inboxes make it easy to listen to new voicemails and recordings, with convenient options to reply with a call back or text message.

Call History

See recently dialed, answered, and missed calls, and easily search for specific contacts and phone numbers in your history.

Call Details

Sometimes you need more info than a simple call history record can provide. Tap the call details icon on any history record to see how the call was routed, where participants were located and more.

Tresta makes it easy to get a new phone number or transfer your current one.

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?
