with specific command-line arguments. If the application is already running, it will process the command without opening a new window.

When a user clicks this link, Windows launches MicroSIP.exe with the argument sip:18005551234 .

MicroSip requires a GUI context in Windows. It cannot easily run as a background Windows Service without user session access. If you need a fully headless SIP API, consider compiling raw pjsua (PJSIP CLI) instead.

Because MicroSIP is built on top of the robust , its core behavior follows standard SIP protocols. To control the running application from external software (like a CRM, helpdesk system, or custom script), you must interact with the Windows operating system layers that MicroSIP listens to. 2. Command-Line API (CLI Arguments) microsip api documentation

def dial_microsip(number): hwnd = win32gui.FindWindow(None, "MicroSIP") if hwnd: data = number.encode('utf-8') cds = struct.pack("IIP", 1, len(data)+1, id(data)) # dwData=1 (DIAL) win32gui.SendMessage(hwnd, win32con.WM_COPYDATA, 0, cds)

Official “API” status MicroSIP does not expose a formal, documented application-level API (e.g., an SDK with callback hooks and rich programmatic control) in the way telephony platforms or PBX software might. Instead, integration usually occurs via one or more of these approaches:

Best for deep, two-way integration where your application needs to react to MicroSip events (like incoming calls). 1. Command-Line Interface (CLI) Reference

The Custom Build form on the MicroSIP website is an extensive "API" for defining a proprietary version of the softphone. Key options include: with specific command-line arguments

cmdCallStart : Runs a command when a connection is established. cmdCallEnd : Runs a command when a call ends. cmdIncomingCall : Runs a command when a new call arrives. cmdCallAnswer : Runs a command when the user answers a call.

MicroSIP allows you to link specific SIP events to command-line actions. You can configure these in the microsip.ini file located in the application directory. Key Event Hooks

In this blog post, we'll delve into the Microsip API documentation, exploring its features, functionality, and potential use cases.

using System.Diagnostics; public class MicroSipAPI private const string MicroSipPath = @"C:\Program Files\MicroSip\microsip.exe"; public static void Dial(string phoneNumber) ProcessStartInfo startInfo = new ProcessStartInfo FileName = MicroSipPath, Arguments = $"-dial:phoneNumber", CreateNoWindow = true, UseShellExecute = false ; Process.Start(startInfo); Use code with caution. 6. Troubleshooting & Best Practices MicroSip requires a GUI context in Windows

using System.Diagnostics; public class MicroSipController public static void MakeCall(string phoneNumber) string microSipPath = @"C:\Program Files\MicroSip\microsip.exe"; ProcessStartInfo startInfo = new ProcessStartInfo FileName = microSipPath, Arguments = phoneNumber, CreateNoWindow = true, UseShellExecute = false ; Process.Start(startInfo); Use code with caution. Python Example: Hanging Up via Subprocess

The format is straightforward: MicroSIP.exe -n sip:123456@your.server.com .

: Used to simulate button clicks like answering, hanging up, or muting. C# Integration Example

You can use SendMessage or PostMessage to interact with the application.
