The Interactions tab in the Sync app is your central workspace for business messaging. From this tab, users can view and manage External SMS conversations, send Direct messages to coworkers, and participate in Channels for group communication.
The Interactions tab supports day-to-day messaging workflows in one place, making it easier to stay connected with customers and team members without switching between separate tools.
Interactions vs Inboxes
The Sync app separates general messaging from conversation management workflows.
- Interactions — Used to send and receive SMS and instant messages, including External, Direct, and Channel conversations.
- Inboxes — Used to manage shared inbooxes with assigned conversations for teams to handling group workflows.
If you need to participate in a message conversation, start in Interactions. If your organization uses shared messaging workflows, some conversations may also be managed through Inboxes.
SMS Registration
SMS capability must be reigstered on assigned user phone numbers. If you need SMS and currently do not have access to an SMS registered phone number, talk to your administoar or reach out to net2phone Canada Technical Support.
