phone.systems™ App Integration Protocols

Integration protocols are predefined rules that enable seamless communication between applications. In phone.systems™, these URL-based commands let systems, scripts, or users perform specific actions such as initiating calls, entering numbers in the dial pad, or authenticating the app.

Benefits of integration protocols:

• Automate repetitive tasks to save time and reduce errors.

• Enable one-click actions to boost productivity.

• Link the phone.systems™ app with other tools to create custom workflows.

• Simplify user experience by reducing manual steps.

For example, a CRM can use these protocols to initiate calls directly from a customer’s profile or embed them in links, emails, or scripts for streamlined workflows.
