The list of methods and their parameters¶
The following table contains a complete list of methods and parameters.
Grey denotes parameters described above or below in the table.
Depending on the direction and destination of the call, different subsets of parameters for the same invocation can be used. For example, in case of the invocation of ConnectionStatusEvent
event, sipLogin
, sipPassword
and other corresponding parameters are passed. In case of an error, the same event ConnectionStatusEvent
will have only two parameters: status
and info
when sending to a client, and status
, info
nodeId
, sessionId
, appKey
when sending to the backend server.
connect | Establishes connection with the WCS Server |
urlServer | This parameter is used by WCS JavaScript API to connect to the server. |
appKey | This parameter passes the REST - URL for the given application to WCS. To view and add applications use the command line interface (CLI). |
sipRegisterRequired |
If this parameter is true, registration on the SIP server is performed by invoking SIP REGISTER . If the parameter is false, registration on the SIP server is not performed. In this case, a web page cannot accept incoming SIP calls, but still can make outgoing calls if the SIP server allows outgoing calls without SIP registration.
