PbxSignal

The PbxSignal protocol is available on AppWebsocket connections to innovaphone PBX objects, if the object is enabled for the PbxSignal api. It allows an application to register to the PBX the same way as this is possible with H.323 or SIP.

    "api": "PbxSignal",
    "src": string,
    "mt": string,
}

api

To address this interface the value "PbxSignal" has tp be used for the api property

src

mt

The message type identifies the requested operation

• Register - Register to a device
• Signaling - Transfer of a signaling message

• RegisterResult - Result of Register
• Signaling - Transfer of a signaling message

{
    "api": "PbxSignal",
    "mt": "Register",
    "src": string,
    "hw": string,
    "flags": string
}
