Upon detection of an MWI message, the FXO device sends a SIP NOTIFY message to the
IP side. When receiving this NOTIFY message, the remote FXS device generates an MWI
signal toward its Tel side.

7.13.4.4 Call Waiting for Remote Extensions

When the FXO device detects a Call Waiting indication (FSK data of the Caller Id -
CallerIDType2) from the PBX, it sends a proprietary INFO message, which includes the
caller identification to the FXS device. Once the FXS device receives this INFO message, it
plays a call waiting tone and sends the caller ID to the relevant port for display. The remote
extension connected to the FXS device can toggle between calls using the Hook Flash
button.
