  • type:

    void

answer

Copy URL
answer(extraHeaders: 

{[header: string]: string}

callerid

Copy URL
callerid(): 

string

customData

Copy URL

The customData value could be sent from WEB/iOS/Android SDKs, and then it becomes the customData value in the Call object. Note that if you receive a value from an SDK, you can always replace it manually. SDKs can pass customData in two ways:
1) when SDK calls the Voximplant cloud
2) when SDK answers the call from the Voximplant cloud. See the syntax and details in the corresponding references: WEB SDK call() / WEB SDK answer() / iOS call:settings: / iOS answerWithSettings / Android call() / Android answer()

Parameters

Returns

  • type:

    string

playProgressTone

Copy URL
playProgressTone(country: 

string

):

void

Provides country-specific dial tones. The method sends a command to the Voximplant cloud to start playing dial tones in the call. The dial tones fully depend on the Voximplant cloud. Note that in order to work properly in a call that is not connected yet, you need to call the Call.startEarlyMedia method before using this function. IMPORTANT: each call object can send media to any number of other calls (media units), but can receive only one audio stream. A new incoming stream always replaces the previous one.

Parameters

  • country:

    string

    2-letter country code. Currently supported values are US, RU.

Returns

  • type:

    void

record

Copy URL
record(parameters: 

CallRecordParameters

):

void

Starts recording the incoming and outgoing audio for this call. This method triggers the CallEvents.RecordStarted event. The default quality is 8kHz / 32kbps; the format is mp3.

Parameters

Returns

  • type:

    void

reject

Copy URL
reject(code: 

number

,
extraHeaders:

{[header: string]: string}

):

void

Rejects the incoming call. First it triggers the CallEvents.Disconnected event immediately. The AppEvents.Terminating and AppEvents.Terminated events are triggered in 60 seconds.

Parameters

  • code:

    number

    SIP status code with the rejection reason. You can pass any standard SIP code starting with 3xx, 4xx, 5xx and 6xx as a reject reason.

  • extraHeaders:

    {[header: string]: string}

    Optional

    Optional custom parameters (SIP headers) that should be passed with the reject request. Custom header names have to begin with the 'X-' prefix. The "X-" headers could be handled by a SIP phone or WEB SDK (e.g. see the incomingCall event). Example: {'X-header':'value'}

Returns

  • type:

    void

removeEventListener

Copy URL
removeEventListener(event: 

CallEvents

,
callback:

Function

):

void

Removes a handler for the specified CallEvents event

Parameters

Returns

  • type:

    void

ring

Copy URL
ring(extraHeaders: 

{[header: string]: string}

):

void

Plays dial tones for the incoming call. The method sends a low-level command to the endpoint device to start playing dial tones for the call. So the dial tones depend on endpoint device's behavior rather than on the Voximplant cloud. IMPORTANT: each call object can send media to any number of other calls (media units), but can receive only one audio stream. A new incoming stream always replaces the previous one.

Parameters

  • extraHeaders:

    {[header: string]: string}

    Optional

    Optional custom parameters (SIP headers) that should be passed with the request. Custom header names have to begin with the 'X-' prefix. The "X-" headers could be handled by a SIP phone or WEB SDK (e.g. see the incomingCall event). Example: {'X-header':'value'}

Returns

  • type:

    void
