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 system can use these protocols to initiate calls directly from a customer’s profile. They can also be embedded in links, emails, or scripts to streamline communication workflows.

phone.systems™ App Supported URL Protocols

The phone.systems™ app supports both industry-standard and custom URL protocols for initiating calls and performing app-specific functions.

Industry-Standard Protocols

The following protocols are commonly used for initiating calls through web links:

Supported Industry Protocols

Protocol URL	Description	Example
callto:some_number	Used to initiate a call using a hyperlink.	callto:12124613663
tel:some_number	Used to initiate a call using a hyperlink.	tel:12124613663

phone.systems™ Custom URL Protocols

In addition to standard protocols, phone.systems™ provides unique URL-based protocols for extended functionality:

phone.systems™ Unique Protocols

Protocol URL	Description	Example
phone.systems://dialpad?number=some_number	Opens the dial pad with a pre-filled number.	Open Dialpad
phone.systems://call?number=some_number	Initiates a call using the phone.systems™ app.	Initiate Call
phone.systems://authenticate?code=some_code	Authenticates the phone.systems™ app with a provided code.	Authenticate

Note

phone.systems™ URL protocols are considered deep links and must be clickable to function properly. When pasted into a browser’s search bar, the URL can be automatically modified, typically by adding a https:// prefix, which may result in an incorrect URL. To avoid this issue, ensure the URLs are clicked to open the app, rather than being pasted directly into a browser’s address bar.
