To sync your phone’s contacts to the Tresta mobile app:
iOS > Settings > Tresta > Enable access to Contacts
Android > Settings > Tresta > Enable access to Contacts
After granting Tresta access to your contacts, you may need to close and reopen the app to see your contacts appear.
Currently, the contacts you sync are not editable from within the Tresta app and are visible only on the phone they were sync’d from. We’re working on a new version of contacts that will allow you to keep business contacts separate from your personal contacts and share contacts across all the users and devices on your Tresta phone system, as well as access contacts in the web app.
