connect method

Future<void> connect({ VINode? node = null, bool connectivityCheck = false, List<String>? servers, })

Connects to the Voximplant Cloud.

Checks whether UDP traffic will flow correctly between device and the Voximplant Cloud if connectivityCheck is enabled (disabled by default).

Optional node - Specifies the node the Voximplant account belongs to.

Optional connectivityCheck - Checks whether UDP traffic will flow correctly between device and Voximplant cloud. This check reduces connection speed.

Optional servers - List of server names of particular media gateways for connection.

Throws VIException if the connection to the Voximplant Cloud could not be established.

Errors:

• VIClientError.ERROR_CONNECTION_FAILED - If the connection is currently establishing or already established, or an error occurred.
