1. Introduction MicroSIP is a lightweight, open-source SIP (Session Initiation Protocol) softphone for Microsoft Windows. It is renowned for its small footprint (under 500KB), low resource usage, and high efficiency. While primarily a GUI application, MicroSIP exposes a powerful yet simple command-line interface (CLI) API that allows external applications to control its telephony functions programmatically.

When MicroSIP runs, it registers itself as a DDE server. Any Windows application that can act as a DDE client (e.g., AutoHotkey, Python with ddelib , C#, PowerShell) can send commands to it. All commands are case-sensitive strings. 3.1 DIAL Initiates an outbound call. microsip api

Alternatives & When Not to Use MicroSIP API MicroSIP API is ideal for lightweight, local automation. For production-grade or cross-platform needs, consider:

def get_call_state(self): hwnd = win32gui.FindWindow(None, "MicroSIP") if hwnd: title = win32gui.GetWindowText(hwnd) if "Dialing" in title: return "dialing" elif "Incoming call" in title: return "ringing" elif "In call with" in title: return "connected" return "idle" def _connect_dde(self): try: self
