Since MicroSIP is open-source, advanced developers can modify the source code directly to add custom API hooks or events. Source Access MicroSIP source code is available under the GPL v2 license. PJSIP Stack : It relies on the PJSIP library
microsip.exe [command] [arguments]
: microsip.exe [number] (e.g., microsip.exe 123456789 ) Answer an incoming call : microsip.exe /answer Hang up all active calls : microsip.exe /hangupall Launch minimized : microsip.exe /minimized Specify a configuration file : microsip.exe /i:filename.ini Close the application : microsip.exe /exit 2. Event Triggers (Inbound Automation) microsip api documentation
To get started with the Microsip API, developers should:
MicroSIP does not currently have a comprehensive, natively published public API for general remote control. However, developers and advanced users typically interact with it through , configuration file manipulation , or by leveraging the underlying PJSIP stack . 1. Command Line Interface (CLI) Event Triggers (Inbound Automation) To get started with
You can pass arguments to the MicroSIP.exe executable to trigger actions instantly. This is useful for building dialers in other software. Basic Launch Parameters
The simplest way to interact with MicroSip is by passing arguments to the main executable ( microsip.exe ). If MicroSip is already running, executing these commands will control the existing instance rather than opening a new one. Triggering an Outbound Call Command Line Interface (CLI) You can pass arguments
This comprehensive developer documentation outlines how to control MicroSIP, capture real-time call states, and embed it into your custom applications. 1. Controlling MicroSIP via Command Line
using System; using System.Runtime.InteropServices; public class MicroSIPController [DllImport("user32.dll", SetLastError = true)] private static extern IntPtr FindWindow(string lpClassName, string lpWindowName); [DllImport("user32.dll", CharSet = CharSet.Auto)] private static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, ref COPYDATASTRUCT lParam); private const uint WM_COPYDATA = 0x004A; public struct COPYDATASTRUCT public IntPtr dwData; public int cbData; public string lpData; public static void SendAction(string actionCommand) // Find the MicroSIP window instance IntPtr hWnd = FindWindow("MicroSIP_WindowClass", null); if (hWnd == IntPtr.Zero) Console.WriteLine("MicroSIP is not running."); return; byte[] snoop = System.Text.Encoding.UTF8.GetBytes(actionCommand); int len = snoop.Length; COPYDATASTRUCT cds; cds.dwData = IntPtr.Zero; cds.cbData = len + 1; // Include null terminator cds.lpData = actionCommand; SendMessage(hWnd, WM_COPYDATA, IntPtr.Zero, ref cds); // Usage: // MicroSIPController.SendAction("action:dial?number=1234"); // MicroSIPController.SendAction("action:hangup"); Use code with caution. 4. Web Integration via URL Protocols
You must open and modify microsip.ini manually while MicroSIP is closed. Locate or add the following keys under the primary settings block: INI Configuration Key Event Trigger Description Argument Passed Triggers immediately when an incoming call rings. Remote Caller ID cmdCallAnswer Triggers exactly when the user clicks answer. Remote Caller ID cmdCallStart
