A: No. But you can wrap its DDE API with a local HTTP server (Node, Python, etc.) to expose REST endpoints.
When you run a MicroSIP command while an instance is already running, the new command communicates with the active process. This execution triggers actions without launching duplicate application windows. Core Command-Line Arguments Command Syntax Description Example Usage microsip.exe number Dials the specified number or SIP URI immediately. microsip.exe 101 microsip.exe -dial:number Explicitly commands MicroSIP to dial the number. microsip.exe -dial:18005550199 microsip.exe -hangup Terminates the active call or rejects an incoming call. microsip.exe -hangup microsip.exe -answer Answers a ringing incoming call. microsip.exe -answer microsip.exe -minimize
Inside MicroSIP's native configuration settings, navigate to . MicroSIP allows you to define an external application executable file to launch upon specific trigger states: On Incoming Call : Executes a command when the phone rings. On Call Answer : Executes a command when the call connects. On Call End : Executes a command when the call terminates.
A complete integration project like this typically includes several moving parts: microsip api documentation

MicroSIP doesn't use INI files for everything. Complex data, such as contact lists and call history, is stored in custom XML files. This XML system is essentially an internal API for structured data storage.

For developers needing to go beyond configuration and integrate with MicroSIP's internal architecture, there is a wealth of information available in the project's source code (hosted on GitHub) and documented on resources like DeepWiki.

When PJSIP receives a SIP message from the network, it calls the appropriate MicroSIP callback. This callback then posts a Windows message to the main application thread, which safely updates the UI. For instance, when on_incoming_call fires, it results in the incoming call dialog appearing on the user's screen. This architecture is critical for anyone looking to understand or extend MicroSIP's core communication logic.
