Microsip Api Documentation __link__ File

MicroSIP is a popular, lightweight, open-source SIP softphone for Windows based on the PJSIP stack

. While MicroSIP itself does not offer a traditional web-based REST API, it provides several integration methods for developers looking to automate calls or connect it with CRM systems. 1. Command Line Interface (CLI) Integration

The most common way to interact with MicroSIP programmatically is via command-line arguments. This allows external applications to trigger calls or hang up. Make a Call command followed by the number or SIP URI. microsip.exe /dial:123456789 Use code with caution. Copied to clipboard : Terminate the active call. microsip.exe /hangup Use code with caution. Copied to clipboard Answer Call : Automatically pick up an incoming call. microsip.exe /answer Use code with caution. Copied to clipboard 2. URL Protocol Handling (Click-to-Call) MicroSIP registers standard SIP and Tel protocols

in Windows. You can trigger a call from any web browser or application by using a hyperlink: sip:number@domain.com tel:+123456789 3. Settings Configuration ( Microsip.ini microsip api documentation

For automation involving user credentials or network settings, developers can manipulate the Microsip.ini

file located in the application's data folder. Key fields include: : SIP proxy address. : SIP extension identifier.

: Encrypted or plain text credentials (depending on version). 4. Advanced: PJSIP Library Customization Available placeholders:

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

, meaning you can implement any feature supported by PJSIP, such as custom event notifications (on_call_state) or message handling. 5. Third-Party Wrappers

Community-led projects often create wrappers to bridge MicroSIP with other environments. Microsip-API (GitHub) : Some developers have created PowerShell or Python wrappers %number% – Caller ID or dialed number

to monitor the application window or logs to detect incoming calls for CRM "screen pops."

However, MicroSIP does have two automation interfaces:

Key Configuration Sections

4.1 Configuring MicroSIP.ini for Callbacks

Edit the MicroSIP.ini file in %APPDATA%\MicroSIP\:

[General]
OnIncomingCall=C:\path\to\your_script.exe %number%
OnCallStarted=C:\path\to\your_script.exe started
OnCallEnded=C:\path\to\your_script.exe ended
OnStatusChange=C:\path\to\your_script.exe %status%

Available placeholders:

• %number% – Caller ID or dialed number.
• %status% – Text status (e.g., "Ready", "InCall").
• %duration% – Call duration in seconds (on ended).

1. Call Control (Make & Hangup)

• Initiate calls from external applications (e.g., click-to-dial from a CRM).
• Hang up active calls programmatically.
• Answer incoming calls automatically or via script.
