When a user clicks these links, the host operating system intercepts the request and passes the phone number string directly to the active MicroSIP instance. 5. Event Handling & Inbound Automation
Microsip is a popular open-source SIP (Session Initiation Protocol) client that allows developers to integrate voice and video communication into their applications. The Microsip API provides a robust set of tools and libraries that enable developers to build custom SIP-based solutions. In this article, we will provide an in-depth look at the Microsip API documentation, covering its features, functionality, and usage.

Your application finds the window handle ( HWND ) of the MicroSIP process and sends a formatted string via WM_COPYDATA . Conversely, your application must create a hidden window to listen for messages sent from MicroSIP. API Command Strings (Sent to MicroSIP) microsip api documentation

MicroSIP supports basic command line switches for automation and deployment:
To automate or integrate MicroSIP into your workflow, you can utilize its command-line interface and configuration-based event triggers. While MicroSIP does not have a traditional REST API out of the box, it offers several ways to control the application and respond to call events. 1. Command Line Interface (Outbound Control) When a user clicks these links, the host
To get started with the Microsip API, developers should:

To initiate a call to a specific phone number or SIP URI, pass the number as an argument to the main executable. If MicroSIP is already running, this command will pass the instruction to the active instance. microsip.exe dialstring Use code with caution. Standard Phone Number: microsip.exe 123456789 SIP URI: microsip.exe sip:username@sip-provider.com
: When passing phone numbers via the URL handler or CLI arguments, strip out spaces, dashes, and parentheses () , leaving only digits or valid SIP alphanumeric strings to prevent parsing failures.
The —spanning command-line parameters and DDE commands—is a hidden gem for Windows VoIP automation. While it lacks modern REST or WebSocket interfaces, its minuscule footprint and deterministic behavior make it ideal for:
