Use the SendMessage action in MicroSIP.ini to broadcast to another window: microsip api documentation

Specifies the location of the microsip.ini file. This allows running multiple instances of MicroSIP with different configurations. Example: MicroSIP.exe /i:folder402\microsip.ini Call Initiation (SIP URI)

| DDE Command | Parameter | Action | |-------------|-----------|--------| | Dial | number | Initiate a call. If call active, puts current on hold. | | CallTo | number | Same as Dial, but does not hold existing call. | | Hangup | (none) | Terminates active call. | | Answer | (none) | Answers incoming call. | | Reject | (none) | Rejects incoming. | | Hold | (none) | Holds/unholds current call (toggle). | | Transfer | number | Blind transfer active call to number. | | SendDTMF | digits | Sends DTMF (RFC 2833). Use , for pause. | | Mute | (none) | Toggles microphone mute. | | VolumeUp | steps | Increases speaker volume by steps (1–10). | | VolumeDown | steps | Decreases speaker volume. | | SetVolume | 0-100 | Absolute volume. | | SetMicVolume | 0-100 | Absolute mic level. | | SetDevice | input/output, deviceID | Switch audio device (see below). | | Status | (none) | Returns current call status as DDE string. | | Close | (none) | Exits MicroSIP. |

Typical use cases for integrating MicroSIP

For real-time integration without launching new processes, MicroSIP listens for Windows WM_COPYDATA messages. This allows you to control an existing instance from another app (e.g., C#, C++, AutoHotkey, or Python with win32gui ). If call active, puts current on hold

// Send an INVITE request sip_invite("sip:remote@endpoint.com", "audio");

: Used to pass string parameters (like phone numbers to dial) between a third-party application and MicroSIP.
